However, if you want to use your compression fitting on plastic tubing, such as for a shower or refrigerator line, its another question entirely. Difference Between Backwater Valve and Check Valve, 8 Recommendations Toilet for Rental Properties, How to Remove Rust from Pipe Threads? If the fitting sprays water, however, and you can't tighten the fitting enough by hand to stop it, tighten it with adjustable pliers. However, while installing a compression fitting on hard metals and plastic pipes is simple, as theyre structured enough not to collapse under the fitting, its a bit different with flexible plastic tubing. Bevel the edges of the pipe with a file. Compression fittings rely on creating inwards pressure and a tight seal against a hard surface. Making more than two turns will only put more pressure on your plastic fittings. When you push the pipe into the fitting, a lock ring grips the pipe. It may rupture from the pressure. Some codes require a primer (the purple product shown in the photos). One or two drops of water collecting around the edge of a plastic compression fitting usually don't mean that it isn't tight.

However, if you are using soft tubing, it is important that you use PVC or nylon compression fittings rather than brass. Insufficient tightening of the compression nut will not deform the ferrule enough to create this contact, but over-tightening will deform the ferrule too much, creating a surface contact. Besides being beveled, they should be completely free of plastic shards. Its essential to choose the proper type of compression fitting for your project. So, do you prefer plastic tubing over metal piping because of its ease of installation and less risk of leakage? This article demonstrates how to cut, join and run CPVC water lines. Use your finger to pull out any debris from inside the pipe. A wrench may damage the fitting. 3. Use another wrench to tighten the compression nut about one-half to three-quarters of a turn.

Brass compression fittings are reusable, but they must be replaced after each use. And most importantly, how to correctly tighten the nut to avoid leaks. Install a brass compression valve on CPVC pipe in almost the same way you would install it on copper pipe. 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. There are many reasons to install a compression fitting rather than a screw fitting or solder. The way in which metal tubing is produced can have a significant effect on its performance with compression fittings. Tighten the cutter so the cutting wheel is snug against the pipe. Note: Never use CPVC for compressed airlines. Next, screw the compression fitting onto the tube. Next up, cut the tubing using a pipe cutter and remove the old ferrule. As described in the Ferrules section above, the optimal seal is created by a line contact between the ferrule and the tubing. Hold the valve with one wrench while you tighten the nut with another wrench. 2. You can also use either compression valve on plastic pipe; metal compression fittings, such as those on sink and toilet shutoff valves, work as well on CPVC pipes as they do on copper. Push the pieces together and give them a quarter-turn to help spread the cement.

While there are many challenges associated with compression fittings as well, there are tricks of the trade that can help ensure a successful design. The acetal copolymer sleeve resists creeping and stress caused from compression. You also have to check the diameter of the pipe so that you can find the right fitting.-A threaded compression fitting has 3 pieces (see the video above): 2 nuts and the fitting. Common choices include metallic tubing (such as stainless steel or copper) and stiff plastic tubing (such as PEEK, nylon, Teflon, Kynar, or polyethylene). This is then bent and squeezed tightly against the tapered surface of the fitting as a nut on the pipe is tightened. The alcohol will lubricate the stainless steel surfaces during assembly, and then evaporate completely, leaving no residue or contaminants behind. Contact your local plumbing inspector to see if CPVC is permitted in your area. Once the pipe and fitting are together, you slide the ring against the fitting, then thread the nut onto the fitting. This will allow you to tighten the nut and pull the end of the pipe tightly against the internal O-ring. If the compression fitting leaks, use both wrenches to tighten the compression nut gently until the leak stops. Be careful not to overtighten the nut. Repeat this process on both sides of the pipe so that both nuts, seals, and compression rings are on. And this is where a compression fitting comes in. These fittings arent normally used in new constructions but rather, renovation projects. You can also go low-tech and use a fine wood saw in a hand miter box. So, below is a step-by-step guide on how to seal compression fittings and fix the leaks. Be aware that many home copper or steel water pipe systems are used as grounding for electrical wiring. As you tighten it, the tubing is pushed inside the O-ring. While they do cost more, the increase in safety can be considerable.

Fit the compression fitting onto the pipe (or fit the pipe into the fitting, as applicable) until the pipe stops inside the fitting. This increases the ease of assembly in applications where many fittings are used, and assembly time is critical. It is also important that the end of each section be squarely cut, to allow the tubing to sit symmetrically in the fitting body. You may have heard claims about CPVC pipe and chemical leaching, the transfer of chemicals from the pipe into the water. Mixing and Matching Components To ensure that the fitting is properly seated, what I like to do is tighten it ever so slightly, then hit the back of the fitting to ensure its seated properly, as opposed to hitting it without tightening it, it would bounce back and not seat properly.

It is crucial in these applications that ferrules designed to resist galling are used. While an elastomeric seal can deform to match these slight variations, the metal-to-metal seal of a compression fitting is less forgiving. Refrigerators and other coolant lines normally arent strong enough for brass compression tubing, even with an insert. But for a better fit, chamfer the edge with a pocket-knife. 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. The success of compression fittings in a given application can depend on a number of factors. In our photo series, we show you how to run the hot and cold water supply lines to a basic half bath (sink and toilet).
