If you use a saw, remove the burrs from the saw cut. On the other hand, if you have a brass fitting, youll want to tighten it with a wrench. The ease of assembly and disassembly is one of the reasons why compression fittings are so widely used. Youll feel some resistance as you slide the tubing past the gripper ring and then more resistance when the tubing slides into the O-ring. Compression fittings are not safe to use on gas lines. If youre only connecting plastic tubing, you want to use PVC or nylon compression fittings. Scrape away any burrs from the copper pipe and rub a drop of dishwashing liquid on each end of the copper to act as a lubricant. Make sure its tightly in place. How to Install Compression Fittings. 1 Step 1: Cut the tube cleanly, preferably with a tube cutter. 2 Step 2: Remove any internal burrs. 3 Step 3: Loosen nut approximately half a turn & insert tube as far as internal stop. 4 Step 4: Hand tighten then tighten nut with two wrenches until firm. We will also discuss the importance of choosing the right type for the job and provide tips for a successful installation. 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. Follow the identical procedure, including applying dishwashing liquid to the ends of the tubing. Compression nuts are threaded, meaning that the number of rotations of the nut is directly correlated to the linear compression of the ferrule, based on the threads pitch. Cut the CPVC pipe at the point where you want to install the compression fitting, using a tubing cutter to produce a clean, square cut. Therefore, you want to use nylon or PVC.
