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. 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. Do not use a wrench. Dont use a wrench to tighten the nut. As described in the Ferrules section above, the optimal seal is created by a line contact between the ferrule and the tubing. Or, if youre using PEX and PVC, a PVC compression fitting is your best option. One piece ferrules are often available as asymmetrical or symmetrical. This is a belt and suspenders design approach, but has proven highly effective in solving the cold flow leakage issue. After that, turn the nut 1/2 of a turn in the clockwise direction to tighten it. Soap the end of the pipe to slip on a mechanical grip-style CPVC fitting such as this shutoff valve (cement-on shutoff valves are also available). Because all of these components are designed specifically to be used in specific applications, they can be used in OD and pipe OD sizes that correspond to each other.
