The concept of push in fitting has been around for decades, yet it has only seen significant growth in the U.S. water market since the early 1990s. Since then, push in fitting have been—by many accounts—the fastest-growing technology change in the water industry.

With their initial entrance into the U.S. water markets in the mid-1980s, push in fitting had to overcome many obstacles of misperception. Dealers and installers couldn’t believe something so simple could work reliably. Old methods of connecting tubing (compression and barbed fittings) were difficult to let go for fear of trying something new and innovative. However, as leading edge technologies were changing the water market, more and more installers and OEMs started enjoying the labor-saving and reliability benefits of push in fitting. The rapid acceptance of push in fitting during the 1990s has established them as the connection technology standard for today’s water industry.

Applications
push in fitting have found their place in the water industry. Their most common use is for general tubing connections in RO and water filtration systems. However, push in fitting are also used on water valves, tanks, pumps and faucets to ease installation and increase system reliability.

Push in fitting can also be found in installations of water fountains, water coolers, ice machines, juice and beverage dispensers and coffee brewers.

Fitting Construction
While push in fitting require complex engineering design and precise, high-quality manufacturing to produce, they are quite simple to understand and utilize.

Push in fitting are made up of three basic components—the fitting body, a flexible “collet” and an O-ring.

The fitting body can be made from metal (brass, stainless steel) or plastic (acetal, polypropylene). The body has an internal geometry to precisely house the collet, O-ring and tubing when assembled. Fitting bodies come in many configurations such as tees, elbows, unions and threaded connectors.

The collet is typically made from plastic with stainless steel gripping teeth molded into its flexible legs. The collet teeth provide a firm grip on plastic or copper tube. The flexibility of the collet legs allows for easy insertion and release of the tubing.

The O-ring is usually made of a food-grade rubber compound (nitrile, EPDM). It is seated inside the fitting body and forms a seal on the outside diameter (O.D.) of the tube.

Installation
As with any product, proper installation is critical to accurate performance and reliability. Care should be taken with any type of fitting to ensure generally accepted, good installation practices are employed. There are certain key points to remember, specific to push in fitting, to ensure a quality installation:

Tubing. Some push in fitting are limited for use with either plastic or copper tubing. A few are capable of handling both plastic and copper without any change to the fitting. Always check with the manufacturer to ensure tubing compatibility. Tubing should be of sound quality. Ensure that tube dimensions, tolerances, roundness and surface finish are consistent with the manufacturer’s recommendations.

Threads. Many push in fitting allow transition from threads to push-in connection. There are various types of threads used such as NPT, NPTF, flare, compression, BSP and BSPT—in straight, tapered, male and female configurations. Again, check the manufacturer’s specifications to ensure correct mating of threads. Also, most plastic threaded push in fitting need only be hand-tightened. Over-tightening may cause stress fractures and result in leaks. Your manufacturer’s catalog should give tightening torque value guidelines.

General practices. When making a connection with a push-in fitting, it is essential the tube is cut square and is free of score marks, burrs and sharp edges. A quality guillotine-style tube cutter should be used for plastic tubing, while a plumber’s pipe cutter should be used for copper tubing. The tube is inserted through the collet, then past the O-ring, all the way to the tube stop. The tube should be pushed in as far as it can go. This ensures the tube is fully inserted and properly seated. The collet holds the tube in place, while the O-ring seals on the tube O.D. It is a good practice to pull on the tube to verify it is secure, and then test the installation prior to use.

One of the benefits of push in fitting is that installations can be quickly disconnected for service. The tube can be removed by simply pushing the collet in squarely against the fitting. With the collet held in this position, tubing is pulled straight out. Generally, both fitting and tubing can be re-used.

Technical Specifications
In the water industry, virtually all push in fitting are made from plastic—commonly acetal or polypropylene. Operating parameters of pressure and temperature may vary from one installation to another. Care should be taken to ensure that application operating parameters are within the fittings manufacturer’s guidelines. Check the manufacturer’s catalog for technical specifications.

Generally, plastic push in fitting are suitable for pressures from vacuum to 150 lbs. per sq. in. (psi) of pressure, temperatures from 33° to 150° F, and tube O.D.s from 1/4- to 1/2-in. Tube O.D. tolerances should be +.001/-.004 in. to ensure proper sealing on the O-ring. In applications where harsh chemicals are present, the manufacturer’s chemical compatibility chart should be referred to. This can be especially important for system cleaning and sanitizing procedures.

Benefits
When compared with the older methods of connection, the benefits of push in fitting begin to stack up quickly.

With compression fittings (metal or plastic) the various bit parts (nuts, ferrules, etc.) must be assembled as part of the connection procedure. Trying to find a dropped nut or ferrule while working beneath a sink is not a very productive use of time. Also, in tightening the compression nut, the question of “how tight is tight enough?” usually comes up.

Similarly, with barbed fittings, the barbed inserts are forcefully pushed into the tube I.D. and then secured by tightening a tiny clamp over the connection. Tees, elbows and other multi-connection fittings become quite a chore to assemble.

push in fitting eliminate the difficulties associated with these older methods. The components of push in fitting are self-contained, insertion is simple and quick, and thread tightening can be done by hand. No pipe dope, sealants or special tools are needed.

In addition, because they are plastic, push in fitting lend themselves better to applications where lead exposure from brass is a concern. Their light weight and small size also make them easy to ship and receive and carry around.

Components and Accessories
Many push in fitting manufacturers offer component part sets that allow push-in technology to be incorporated into product housings. The part sets typically include a metal or plastic “cartridge” insert that presses into a pre-determined port in the housing. The collet snaps into the cartridge after the O-ring is pushed down into its seat. This allows for an integral push-in connection to valves, filters, pumps, etc. Such component part sets are employed at the OEM level, making the OEM’s products more user-friendly and thus more marketable.

Various accessories enhance the use of push in fitting. These include locking clips, collet covers and threaded stem adapters to make swivel combinations.

Conclusion

The growth in the use of push in fitting has been fueled by the needs of dealers and installers to enhance productivity, increase reliability, and reduce overall costs. However, one must remember that any product is still only as good as the company that makes it. Areas such as customer service, technical support and training should always be considered when selecting a push-in fitting brand. In addition, the manufacturer should have a strong distribution network and trained sales personnel, as well as provide marketing and promotional support.

Understanding the concept of aromatherapy is quite simple if one simply analyzes the word itself, namely it’s a type of therapy that relies on fragrances, aromas or smells. The pure form of this practice, though, relies on the use of natural plant extracts, with no synthetic or artificial ingredients to speak of. Aromatherapy has many applications including the treatment of many emotional and physical issues as well as for simple relaxation. In this article we will be looking at aromatherapy and essential oils, covering some interesting and useful facts.

Aromatherapy is an excellent way to relieve stress, which is probably one of the best things to be said about it. Stress plays a big role in many health issues, including psychological problems such as depression and anxiety. This isn’t to say that aromatherapy is an instant cure for such potentially serious problems, but it can definitely help. Lavender, clary sage, eucalyptus and sandalwood are a few of the many essential oils that can help with relaxation. The even better news is that you can relax naturally, without needing to do anything else, by simply inhaling these fragrances or vaporizing them in the atmosphere.

The fragrance of essential oils can be dispersed throughout a room or home with the help of a diffuser. Electric diffusers are the most popular, despite the fact that there are a wide range available for sale. This is a device you plug into the wall and it dispenses the scent of the essential oil into the air with a fan. The nebulizer, another gadget used to dispense essential oil fragrances, literally breaks down the oil into separate atoms before permeating the atmosphere with them. Plenty of people feel that this method allows one to absorb a higher degree of the helpful traits of an essential oil. Another way to disperse the fragrance of an essential oil throughout a room is with the help of a lamp ring, which is placed over a bulb, with a few drops of oil in it, and the heat then diffuses the oil into the room.

Alertness, relaxation and mood improvement are only a few of the benefits of aromatherapy sessions.

Depending on how one looks at it, it can be concluded that aromatherapy can be both simple as well as complex. Our desire to experience lovely fragrances is what lies at its foundation, which is what makes it so uncomplicated. It gets complicated, though, because there are an almost endless number of plants that we can use for this purpose. Considering that each separate aroma can be blended with others to create a unique fragrance, then the possibilities increase exponentially. However, to gain all the advantages of aromatherapy, you simply need a few fragrances that you enjoy.

Not only are massage beds convenient and relaxing, they can also benefit your health. Studies show that massage can be useful for reducing stress, one of the biggest threats to your health. With a massage bed, you can enjoy the luxury of a massage anytime. We’ll be looking closer at some of the options available for massage beds so keep reading to learn more.

Even though massage beds are seen as a luxury and are the definition of comfort, there are certain issues you need to know first. For certain people, such as someone who is disabled, elderly or pregnant, massage beds can pose certain risks that you should be aware of. Pregnant women, for example, should stay away from automatic massages as they can be dangerous and they should rely on professionals who know what they are doing. For someone elderly, or anyone who has a disability that makes it difficult to get up and down easily, supervision is recommended when using any kind of massage bed. While, in principle, there is no danger to using massage beds, some people shouldn’t be left alone when they are using them.

Some massage beds can used for other purposes such as providing facials because of their included features.

These are the type of units you’d find in a spa for clients who might be getting a massage and/or a facial, but you can also have one in your home, or perhaps workplace. These massage beds allow you to adjust the position of your legs and can be adjusted to be used in a seated position or while lying down. These are a good option for someone who gets frequent massages or for a massage therapist who needs a versatile massage bed.

An expert can give you a recommendation if you’re not sure what type of massage bed is right for you. You can ask your chiropractor or massage therapist if you see one. Don’t think that they won’t help you because of concern for losing your business. If you need or like to get occasional massages or adjustments, you’re still likely to go see them even if you have your own massage bed. If you don’t know any experts that you can ask, try posting an inquiry to a natural health or massage based discussion forum.

Many people see having a massage bed as a necessity in today’s stressful world not just as a modern luxury. Their many health benefits make massage beds a worthwhile investment. The massage beds discussed above are some of the leading styles available so keep them in mind while you shop. Only you can ultimately decide what type of massages or treatments will do you the most good.

Known officially in the state of Florida as Coventry Health Care, Vista is the private label HMO product which is probably considered by many Florida residents to be pound for pound the best insurance money can buy right now at at time when health care seems to be escalating in terms of price yet decreasing in terms of benefits. Normally plans like these are offered for large scale group employers and not to the public at large.

This product is considered an HMO which means it is a Health Maintenance Organization, otherwise known as managed care. In a managed care setting insurance companies determine the care that a insured has access to or not so it has a certain level of pros and cons inherently built into the plan. One of the main advantages from the insured’s standpoint is that the cost is ultimately a lot cheaper than a traditional PPO product. So if you are a Florida resident and are price shopping this plan might be the right fit for you.

For example with a PPO, if you want dental or vision, guess what this is extra and means you pay more these benefits. With an HMO product like Vista, these benefits are all inclusive and guess what? It is often a lot cheaper. So how can you get this type of coverage? Well, even though these benefits are normally available to groups or companies, unfortunately you have to go through a process called medical underwriting. Medical underwriting is the process in which an insurance carrier takes a retrospective review on your medical history to determine if you can or cannot be provided the insurance applied for.

Medical underwriting is something which is almost impossible to avoid when trying to obtain individual health insurance coverage. The process is the insurance carriers way of determining if the premium paid by the insured member will justify his or her cost in terms of medical expenditures. Even though the whole process might seem to be somewhat of a pain, it might be worth your time and money if one can actually qualify for the health plan.

There are many reasons that fitness training is so important. Besides the obvious fitness training isn’t really that hard. Even getting up and walking around for fifteen minutes or so can do a world of good for those who aren’t necessarily in the greatest shape. There is more to training than do any hardcore aerobics and weightlifting. Simple things can be good for your body as well as your mind.

For example fitness training can do a world of good when it comes to great circulation. If you increase your circulation and get your blood pumping every now and then you can help any heart problems you may have as well prevent them if you don’t have them. This is because it has been shown that even losing a few pounds can lighten the load on your circulatory system and allow your heart some relief. This can easily be achieved by just taking a short walk around the block. Just getting fifteen minutes a day of some activity can greatly impact your life.

Another great advantage to fitness training is that it can relieve a lot of fatigue. This is because it gets your blood pumping and some adrenaline going. While you may think that you are too tired now to move, if you get up and do some exercise you will find that a lot of that afternoon slump will disappear. This once again only requires getting up for a mere fifteen minutes and walking around. If you have to work, take walks on your breaks and you will be surprised at how good you feel and how much more work you can get done. There are even some countries that encourage it, but even if you don’t live in one of those, you surely can take some of your break time to go on a short walk. You’ll be glad you did when you see how refreshed you feel.

One last obvious benefit to fitness training is losing weight. There are many people nowadays that are overweight and looking to lose some of the weight. Whether it is a minor amount of weight to a lot, it’s nothing that a little fitness can’t help. Once again even if you just lose a little weight you will feel better all around. Losing weight can also help improve a number of health problems and should be taken advantage of.

When it comes to fitness training, there really isn’t any good reason not to do it. In fact the advantage far outweigh the disadvantages. Just remember to check with your doctor before starting anything and you will be glad you did.

Oftentimes workouts at home tend to focus on aerobic and strength training exercises in order to improve physical conditioning, and there is no doubt that such a program can be effective for many. But another key ingredient of physical health can go unnoticed if you aren’t careful and that is flexibility of the muscle groups of your body. Strong muscles that aren’t flexible can be prone to injury, so pilates exercises help round out a good home fitness exercise routine.

In case you are wondering what pilates is, it’s a system of strengthening the mind and body through a set of movements that emphasize proper breathing and posture. It was initially developed by Joseph Pilates almost 70 years ago to help him overcome some persistent childhood sicknesses. It worked so well that he began to teach others his system for personal exercises using body resistance. As others began to see benefits the word spread and now pilates has millions of adherents and practitioners who use it regularly to stay in shape.

When using a home gym you tend to focus on certain muscle groups and target them to the exclusion of others. There is nothing wrong with this but inserting some pilates movements into your daily workout routine can help make sure that all your muscles get the attention they need. It also helps insure that the muscles that you are building also retain a good measure of flexibility rather than just size alone. As we age flexibility becomes much more critical and so pilates works especially well in this area for people who are middle-aged and up.

If you want to build big muscles, pilates will not accomplish that goal. However, large muscles can make one susceptible to injury if they don’t get the proper conditioning, so pilates exercises can even help the bodybuilding folks if it is used in addition to their muscle workouts. It helps elongate muscles instead of just build them up and places an emphasis on body movement and position. This leads to graceful body movement, and reduces sports injuries.

Pilates focuses on building a strong core in the stomach and back of the individual and so it has also been known to be very effective for patients that have lower back pain problems. Oftentimes, these back pain issues are aggravated by some muscles not being as strong as they should be and causing other muscles to be overworked as a result. Since pilates is so low impact and is usually done in lying or sitting positions it is also usually a very safe exercise to perform, but as always it is good to get a doctor’s approval before you begin any new exercise routine.

If you have been using traditional exercise equipment in your home fitness workouts, maybe it’s time to consider adding in a pilates exercise routine as well. To get started you can buy books and DVDs that can help you learn many basic pilates movements or you can also attend classes and be taught by a good instructor how to set up a pilates routine that will be best for you.
