PEX tubing, or PEX piping, is never glued or soldered as metal pipes are. Fittings are used with cinch clamps to bring pieces of pipe together can create elbows and bends in the pipe. \
Because PEX comes in long rolls, you won't need to use a lot of fittings to install PEX. However, it does need to be supported every 32 inches when running horizontally and every four to six feet when vertically installed. \
PEX must have these supports because PEX cannot be pulled tight. \
