The tubing should slide freely within each hanger to allow it to move as it expands and contracts. The black acetal copolymer also resists ultra-violet ray attack and has excellent dimensional stability. Add shutoff valves using mechanical fittings as well. The way in which metal tubing is produced can have a significant effect on its performance with compression fittings. Save my name, email, and website in this browser for the next time I comment.

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. You can also use a stab-in tee to connect PEX fittings supply to CPVC. For more information, visit brasscraft.com. Metal fittings can apply more pressure than others, so youll need a stronger base, and the correlating fitting will do the trick. However, it is important to do so carefully.

Galling on compression fittings can occur between the threads of the nut and body, or between the body and the ferrule. CPVC is not as tough as copper or galvanized steel. 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. Note: Never use CPVC for compressed airlines. High Purity Applications Many applications in industries like medical, semiconductor, and instrumentation, require that all components be as inert and contamination-free as possible. Such small leaks usually stop in a day or two. This is true, especially if you dont know how compression fitting works with plastic. You may use another wrench to securely hold the compression body.

This can cause leaks to develop over time, as the tubing wall begins to creep (cold flow) away from the ferrule. Besides being beveled, they should be completely free of plastic shards. Next, apply the CPVC cement to the tubing and the inside of the fitting. and 3/4-in. That tapered edge is designed to allow you to press a pipe onto it. Compression couplings and other fittings are also available for CPVC plumbing pipes. Care should be taken to follow the assembly procedures recommended by the manufacturer. Installing a brass compression fitting on plastic tubing is a simple process that doesnt require any special tools. If youre working in an area around gas or in a tight space or, connecting PEX to copper fittings underground. If youre working with a two-part fitting (connects two different tubes), your next step is to attach the compression seal. Make sure it faces the side the compression fitting is on, not the nut. Have the necessary tools for this DIY project lined up before you startyoull save time and frustration. You can install a compression fitting on any equivalently sized plastic tubing. This is then bent and squeezed tightly against the tapered surface of the fitting as a nut on the pipe is tightened. Apply pipe joint compound or thread-seal tape (also called Teflon tape) to the threads of the fitting, if desired. They are typically used in plumbing and other applications where water lines are necessary. Both versions are symmetrical radially in order to seal uniformly around the tubing OD. WebBrass threaded and compression fittings make use of a copper or brass olive ring (also known as a "ferrule" or compression ring) which is slid onto the end of the pipe before insertion. 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 ).

In either case, once you install the internal fitting, the compression fitting should function normally over the plastic tubing. Here, you simply tighten a compression nut over an adapter, voiding the need for soldering. 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. Some manufacturers offer tubing inserts for this purpose. While they do cost more, the increase in safety can be considerable. This type of cutter is designed to produce straight, burr-free cuts on CPVC and PVC tubing. The key to using compression fittings at high pressure, especially with gases, is the integrity of the ferrule seal. If youre joining different materials, such as PEX tubing t. compression fittings are a great choice. What Type Of Compression Fitting Should I Use On Plastic Tubing?
