Therefore, you should never use compression fittings on your gas lines. The tubing must be inserted all the way into the fitting. Now, this is how a compression fitting works with copper. The resulting rotation can cause the ferrule to compress asymmetrically, or to shift over time due to residual torque. Whether its the water heater in your home or a pipe transporting hazardous chemicals, all compression fitting applications have several traits in common: they require easy assembly, long life, and absolutely no leaks.

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 addition, the metal fitting may apply more pressure, which means you want a stronger base. In addition, compression nuts use a tapered thread. But for a better fit, chamfer the edge with a pocket-knife. Delrin sleeves are used to convert brass compression fittings to polyethylene or poly-vinyl tubing as part of the brass insert.

The other part is the locking ring which screws on to the base of the fitting and it prevents the tubing from slipping off the barb. Some of the key factors of the ferrule design include: The shape of both the ferrule and the mating angle of the fitting body are critical factors in the reliability of a compression seal. Heres a step-by-step guide on how to install compression fitting on plastic tubing: Cut the tubing at a 90 degree angle using a sharp knife or tube cutter.

Photo 3: Push on a CPVC compression fitting. Additionally, the relative angles of the ferrule and the fitting body will determine how much linear motion is converted into radial compression, and what level of contact (line contact or surface contact) is made with the tubing. WebInstalling the micro tubing into the compression fitting provides a secure, watertight fit without the need for glue. If youve ever done any soldering, you know that you have to get rid of all the water in the adjacent copper pipes to heat the pipe to accept the solder.
