Even if components from two different manufacturers look similar externally, they will often differ in key internal dimensions, such as ferrule/body taper, ferrule length, and thread size and pitch. Is Dressing up Your Pets Morally Acceptable? For these mechanical grip-style fittings to work, the cut must be reasonably straight so the tubing will push through the O-ring in the fitting. Who Makes Ultra Faucets, And Where Are They Made? But how does the fitting work with plastic? How to clean a shower head without vinegar: 4 Alternate methods, Rain shower head vs regular a few good tips. E.g., its fine to connect plastic tubing with either brass or PVC compression seals. Keep in mind that a crooked cut will have less surface area to cement and a greater chance to leak. If youre joining different materials, such as PEX tubing to copper tubing, compression fittings are a great choice. Caution: Keep a window open for ventilation and use an organic respirator. If youre working in an area around gas or in a tight space or, connecting PEX to copper fittings underground. Tubing should be smooth and free of roughness or extrusion lines that can create a leak path past the ferrule. WebThe first step is to cut the end of the tubing straight. In Apply pipe joint compound or thread-seal tape (also called Teflon tape) to the threads of the fitting, if desired. Contact your local plumbing inspector to see if CPVC is permitted in your area. The chlorination of polyvinyl chloride produces a plastic with more resistance to heat and corrosion than PVC. Cut the end of the pipe, if necessary, using a tubing cutter. This step is absolutely necessary to get a good mechanical (Photo 4) or glued (Photos 5 and 6) connection. Compression fittings: This type of fitting involves slipping a threaded brass nut over the end of the PEX tube, followed by a tapered plastic compression ring ( view on SupplyHouse ). Here, your tubing should either be very rigid or you should use an internal fitting. Compatible with any 1/4 in. Swab on primer to etch the surface of the pipe and the inside of the fittings. 5 Steps to Done it. Likely, none. Some areas dont allow stab-in fittings to be concealed. The resulting rotation can cause the ferrule to compress asymmetrically, or to shift over time due to residual torque. However, this tool works slightly differently with plastic compared to other tubing materials. Then, press the sealing ring onto that. Runs longer than 30 ft. require a U-shaped detour about 1 ft. on a side somewhere in the length to allow for expansion and contraction. Position the Parts and Join Them 3. The cement-on tees, elbows and couplings are considerably cheaper and simpler to use than the mechanical fittings, and because of their small size, fit nicely into tight areas. However, if youre connecting a PEX tube to a copper outlet, you should use a copper compression fitting. The tubing insert, usually made of metal, is pressed into the soft tubing, and supports the tubing wall so that it will not collapse as the ferrule is compressed. Simply, with plastic piping, you have to use an insert or liner. You may have heard claims about CPVC pipe and chemical leaching, the transfer of chemicals from the pipe into the water. In fact, CPVC has been successfully used in homes for more than 35 years. Be aware that many home copper or steel water pipe systems are used as grounding for electrical wiring. Compound or tape provide lubrication to the threads and can help prevent leaks, but valve manufacturers often do not specify using compound or tape with their compression fittings. The success of compression fittings in a given application can depend on a number of factors. Leave a gap, as shown in Photo 8, especially in a long run. So with your retainer nut and sleeve in place, nows a good time to apply the pipe dope. Therefore, if youre installing compression fittings, youll want to add a fitting inside the tubing. Watch carefully for leaks, keeping an eye on the fitting in particular. Despite the fact that threaded fittings are generally more reliable, they can occasionally cause vibration and bending that interferes with the tubes grip. Loosen the nut on the compression fitting and slide the fitting onto the pipe until the end of the pipe is fully inside it. They consist of three components: the sleeve, nut, and fitting body. Yes. However, you may want to replace the rings if the fitting is old. Use your finger to pull out any debris from inside the pipe. Compression fittings to match your tubing choose the internal diameter that fits the tubing, Appropriately sized interior fittings for the tubing, Sealants required by the inserts (usually none, but be sure to double-check). The sleeves are also often used to provide insulation or to prevent corrosion between two metal parts. Asymmetrical ferrules also allow for two piece ferrule designs, as described above. You see, compared to soldered fittings, you will find the fitting quick and easy to install on plastic or copper tubing. Once the pipe and fitting are together, you slide the ring against the fitting, then thread the nut onto the fitting. How to install Compression Fittings on plastic tubing.

Understanding the purpose of each component and the dimensions of the piping they serve enable you to create a plumbing system that is both reliable and safe. There are three primary parts in a compression fitting: a nut, a plastic compression ring, and ferrules. It is important to note however, that compression fittings can only be disassembled and reassembled a few times before either the ferrules and/or the fitting body should be replaced, to ensure a leak-tight seal. It is also important that the end of each section be squarely cut, to allow the tubing to sit symmetrically in the fitting body. This is a belt and suspenders design approach, but has proven highly effective in solving the cold flow leakage issue. Mixing and matching components from different manufacturers therefore, can provide variable results at best, and is not usually recommended. So, the fat end of the taper should face the compression nut while the small taper should go towards the fitting body. Slide the sleeve up to the nut on its threaded side. If youre using copper or brass fittings, use copper or brass internal fittings. You can also cut this pipe with an ordinary fine-tooth saw, but deburr the cut end with a pocketknife, file or sandpaper (See below).

Compression fittings are one of the most common and versatile methods of connecting metal or hard plastic tubing. Youll feel some resistance as you slide the tubing past the gripper ring and then more resistance when the tubing slides into the O-ring. 6 Easy Steps Step 1: Gather your installation tools. Bevel the edges of the pipe with a file. Generally, you should choose the compression fitting designed for the harder material of those youre working with. Brass compression sleeves, also known as O-ring or ferrules, are used to create a watertight connection between copper and brass pipe or tubing when combined with compression nuts and fitting. The cold flow issue is exacerbated when the tubing is exposed to high temperatures, and can occur even when fittings are properly installed and initially leak free. Next up, you need to insert the brass insert inside your plastic tubing for additional support. Hand tighten each nut. If you need to connect to galvanized pipe, use a special threaded connector with a built-in seal exactly like the female CPVC fitting shown in Photo 14. One key design factor when using this kind of tubing is its tendency to cold flow, or deform away from a compressive load. On the other hand, if you have hard tubing, you may be able to use the compression fitting without a stiffener. Plastic tubing offers many benefits compared to alternative piping materials, such as ease of installation and resistance to chemicals. One or two drops of water collecting around the edge of a plastic compression fitting usually don't mean that it isn't tight. Then, screw the compression fitting onto that side of the tube. Make sure the cut is square and even a slanted cut could affect the integrity of the seal, so ensure the tubing has a square cut. Here, youll want to hand tighten the fitting first and then use a wrench to tighten it further. This makes joining easier.
