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. 5.29K subscribers. Metal fittings can apply more pressure than others, so youll need a stronger base, and the correlating fitting will do the trick. Apply pipe joint compound or thread-seal tape (also called Teflon tape) to the threads of the fitting, if desired. The ones shown are specially designed for CPVC plumbing systems. They are most commonly found on water shutoff valves, or stop valves, the type used on faucet and toilet water supply pipes. Be careful not to overtighten the nut. Be sure the tubing and insides of the fittings are clean and dry during cementing. Here, you can normally 2. Hunker may earn compensation through affiliate links in this story.

Theyre just as easy to remove! micro drip tubing or dripline Constructed of UV resistant high-impact plastic, for durability in the landscape This system is designed to be very user-friendly, and because the outside diameter of CPVC tubing is sized the same as copper pipe, the grip-style mechanical fittings (Photos 3 and 4) can be used on both copper and CPVC pipe. Once this happens, your fittings might develop a crack or start leaking. Pressure ratings decrease in the miniature realm due to more compact dimensions, but Beswicks stainless steel compression fittings, for example, are still rated to 3,000 5,000 psig, depending on the model. Simply, with plastic piping, you have to use an insert or liner. Particularly useful for their extreme temperature and pressure capabilities, and their compatibility with aggressive fluids, compression fittings can be seen in systems varying from gas lines in refineries, to the plumbing under your sink. Finally, use a pipe cutter to trim the tubing to the correct length. Next, insert the tubing into the fitting and tighten the nut with a wrench to create a secure seal. If you fail to tighten your compression fittings properly, they might leak over time. Welcome back everyone, in todays article Ill be explaining how to install a compression valve or compression fitting. 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. Compression nuts are threaded, meaning that the number of rotations of the nut is directly correlated to the linear compression of the ferrule, based on the threads pitch. Disassembly and Re-Assembly Because of its flexibility (which can be an asset), youll need to support it more often than copper or galvanized steel-every 32 to 36 in. Smoking is absolutely prohibited while priming and applying cement. If your situation doesnt allow this, you can solder a copper tee with a male adapter and run a threaded CPVC female adapter. Key factors include: pressure and temperature extremes, environmental conditions, vibration conditions, fluid compatibility, and minimum bend radius. Clean the outside of the pipe with a rag; it must be clean, with no paint or other contaminants. Do not use compression fittings in locations where they will be hidden behind wall, ceiling or floor materials. 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.

Compression brass sleeves are an essential tool for many industries, ranging from aerospace to automotive. Compression fittings use a nut, a plastic compression ring, and a seal to create a tight seal on any pipe. It's easy to cut and assemble, using compression of cemented fittings. Chief among these are fitting and ferrule design, tubing selection, and installation procedure. Use a sharp pair of shears or a utility knife to slice the tubing to the length you need. Common choices include metallic tubing (such as stainless steel or copper) and stiff plastic tubing (such as PEEK, nylon, Teflon, Kynar, or polyethylene). If everything remains dry, youre good to go! Go around the tubing several times with the dauber (Photo 6) to work the solvent into the plastic. Avoid over-tightening or you could strip the threads. Most brass compression fittings come already assembled. Torque, on the other hand, can vary greatly, depending on fitting and ferrule material, lubrication, degree of galling (for stainless fittings), and other factors. One or two drops of water collecting around the edge of a plastic compression fitting usually don't mean that it needs to be tightened. Hold the fitting against the pipe, and slide the compression ring up against the fitting. In most cases, 2-3 turns past a hand-tighten are good enough. Instead, the brass fitting may cut the line.

In addition to these general considerations, there are several more specific factors to consider regarding compression fitting assemblies, such as: PTFE tubing is a popular material choice for tubing because it is resistant to most chemicals, handles relatively high pressure, is low out-gassing, and is more flexible than metallic tubing. diameters in 10-ft. lengths. The trick to a leak-free installation is making sure the pipe end is cut square and is smooth and clean. Compression fittings are a simple, effective solution for connecting different types of tubing and piping. This negates the holding power of the ferrule, and can also prevent the ferrule from making a leak-tight seal around the full diameter of the tubing. Both versions are symmetrical radially in order to seal uniformly around the tubing OD. Another method is to solder in a tee and a PEX supply adapter. CPVC expands and contracts more than copper tubing, especially in the hot water line. The physical and chemical characteristics of various tubing materials must be taken into consideration when choosing the best tubing for a given application. Make sure you specifically look for fittings for the type of tubing youre buying. While an elastomeric seal can deform to match these slight variations, the metal-to-metal seal of a compression fitting is less forgiving. Caution: Keep a window open for ventilation and use an organic respirator. Both components must be tapered in a manner that allows the ferrule to compress properly as the nut is tightened, while maintaining axial alignment with the tubing. Web1.

Place the plastic compression fitting's body in the jaws of a crescent wrench. This style of supply line has a 1/2 inch nut at each end. Thats because compression fittings simply unscrew and come off. This is then bent and squeezed tightly against the tapered surface of the fitting as a nut on the pipe is tightened. CPVC is not as tough as copper or galvanized steel. E.g., buy PEX fittings for PEX tubing. Harsh water won't harm the material, unlike copper, which will erode from acidic water. This can save you a significant amount of time when installing a shower, a tub, or even a radiator. Slide the compression nut onto the pipe with the threads facing out. 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. of pipe, then had to spread the gap to get the fitting in place. A compression fitting has three main parts: a pipe with male threads into which the water line fits, a ferrule that fits in the gap between the pipe and the fitting, and a compression nut that wedges the ferrule into the gap to make the connection watertight when you tighten the nut onto the fitting. Fit the compression fitting onto the pipe (or fit the pipe into the fitting, as applicable) until the pipe stops inside the fitting. Insert the Pipe into the Fitting. Scrape away any burrs from the copper pipe and rub a drop of dishwashing liquid on each end of the copper to act as a lubricant. Does wd40 in toilet remove hard water stains?

After that, turn the nut 1/2 of a turn in the clockwise direction to tighten it. First, youll need to measure and cut the tubing to the desired length. This aggressive water can sometimes eat through copper pipe within eight years. You may also want to use pipe dope or PTFE tape. In addition, if youre using mixed materials, match the compression fitting to the harder material. Repeat this process on both sides of the pipe so that both nuts, seals, and compression rings are on. If you can't get a leak to stop, you may have cross-threaded the compression nut, or the compression ring may not be seated properly against the fitting.
