Insert the Internal Fitting and Mixing and Matching Components A inexpensive tubing cutter easily cuts copper pipe. It is good practice to seek technical support from a tubing supplier when working on a new design. 2. In many applications, high pressures and temperatures necessitate the use of hard tubing, which is incompatible with many other types of fittings. 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. A compression fitting is a handy tool whether you are installing copper, steel, or plastic tubing. In most cases, its a good idea to match materials in mixed materials. Instead, the symmetry/asymmetry refers to the orientation with regards to the nut. Re-assembly can be accomplished in a similar manner to the initial assembly, although typically fewer turns of the nut are required, since the ferrule is already swaged to the tubing. Insert your internal fittings into the tube. Its portfolio of products includes water stops, water connectors/supply lines, gas connectors, water heater connectors, drain cleaning products, and hand tools.
