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. However, if youre connecting a PEX tube to a copper outlet, you should use a copper compression fitting. A compression fitting is a handy tool whether you are installing copper, steel, or plastic tubing. An asymmetrical ferrule is cone shaped, and can only be placed into the fitting body in one direction (usually with the tip of the cone facing into the fitting body). When drilling holes through framing members, youll also need to give the piping some space (Photo 9) to allow the longer horizontal and vertical tubing to move. Once you complete the fitting, be sure to check your handiwork. Now, its time to install the fitting. Sealing rings always have a tapered edge. (The O-ring was pulled out for visibility.). Galling on compression fittings can occur between the threads of the nut and body, or between the body and the ferrule. These include: Get your PVC pipe and cut the tubing to your preferred size. Even so, not everyone can install the fitting correctly. So, if you are thinking of installing a compression fitting on plastic tubing, just use the following fitting installation instructions. Here, the joint will never be under pressure. Theyre a safe alternative to soldered fittings in various situations, making them a popular pick. Tighten the tool slightly, and rotate once or twice in both directions again. Cut the end of the pipe, if necessary, using a tubing cutter. Repeat the process on the other end of the compression fitting. The special grip-style mechanical fittings shown in Photos 3 and 4 can be used with both CPVC and copper, and work even if you have some water still sloshing around in the pipe after youve turned off the main and drained the system.

Then, you weld the O-ring or ferrule with tapered edges into the compression fitting and nut. Here, the answer is simple. Furthermore, compression nuts and ferrules are often all metal, and can be autoclaved, cleaned, or sterilized more easily than fittings containing plastics or internal elastomers. The Science Behind Arm Compression Sleeves: How Do They Work And What Are The Benefits? All components work together to create a watertight seal. As the ferrule(s) moves axially into the fitting body, the bodys angled shape radially compresses the end of the ferrule onto the outer diameter of the tubing. The nut compresses the ring between itself and the fitting, and the tapered edges of the ring are wedged tight inside the fitting and the nut, creating a watertight seal. If the Tubing Kinks 4. Before you fit the parts together, you slide a compression nut and a compression ring onto the end of the pipe. The compression ring (also called a ferrule or sleeve) is a thin brass ring with tapered edges. Once the pipe and fitting are together, you slide the ring against the fitting, then thread the nut onto the fitting. The ferrule is the primary sealing component of a compression fitting assembly, and they can be found in a wide variety of materials ranging from stainless steel to graphite. So, the fat end of the taper should face the compression nut while the small taper should go towards the fitting body. They are most commonly found on water shutoff valves, or stop valves, the type used on faucet and toilet water supply pipes. The way in which metal tubing is produced can have a significant effect on its performance with compression fittings. Position the Parts and Join Them 3. Most basic compression fittings contain a single ferrule. This increases the ease of assembly in applications where many fittings are used, and assembly time is critical.

Check with an electrician if you think youve broken the continuity of your electrical grounding. While an elastomeric seal can deform to match these slight variations, the metal-to-metal seal of a compression fitting is less forgiving. Besides being beveled, they should be completely free of plastic shards. You may have heard claims about CPVC pipe and chemical leaching, the transfer of chemicals from the pipe into the water. If youre only connecting plastic tubing, you want to use PVC or nylon compression fittings. E.g., connect to copper with brass and connect to plastic with PVC. Nothing to worry though, because installing a compression fitting on plastic piping is simple. One key design factor when using this kind of tubing is its tendency to cold flow, or deform away from a compressive load. Do not use a wrench. Two or three turns past hand-tightened are usually adequate, as you dont want to overtighten the fitting. You must not overtighten your fittings. 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. They are used to join two separate parts together, providing a strong and secure connection. The key to using compression fittings at high pressure, especially with gases, is the integrity of the ferrule seal. It is this radial compression that creates the leak tight seal between the fitting, ferrule, and tubing, and gives the compression fitting its name. Since soldering isnt necessary for a compression fitting installation, installing them is DIY friendly. Mixing and Matching Components Studies have proved that CPVC tubing and fittings are completely safe for home water supplies.
