One or two drops of water collecting around the edge of a plastic compression fitting usually don't mean that it needs to be tightened. If there is a particular design issue (for example, a tight bend radius) that necessitates softer tubing, it is important to reinforce the tubing wall. (Consult the manufacturer for an MSDS technical data sheet.) 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.

It is also important that the end of each section be squarely cut, to allow the tubing to sit symmetrically in the fitting body. Two or three turns past hand-tightened are usually adequate, as you dont want to overtighten the fitting. The functioning principle of each component also remains more or less the same between designs: tubing is inserted into the end of the fitting, and the nut/screw is tightened, forcing the ferrule(s) into the fitting body.

Also, compression fittings can be used on leaky pipes such as broken water lines in an emergency situation. Separate each piece of the fitting, including the nut, ferrule, body, and stiffener, setting each piece within reach. tubing and 1-in. Both components must be tapered in a manner that allows the ferrule to compress properly as the nut is tightened, while maintaining axial alignment with the tubing. Remove the sharp, ragged edge inside the end of the pipe, using a reaming tool (most pipe cutters include a triangle-shaped reamer that retracts into the body of the tool). 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.
