PEX fittings are joined with?

Explanation:
PEX piping uses mechanical joining methods rather than adhesives. The joints seal by deforming a ring or ferrule around the pipe as it seats into the fitting. The two common methods are crimp and compression. In a crimp system, a metal crimp ring is placed over the PEX and a tool squeezes the ring tight around the fitting to create a watertight seal. In a compression system, a nut and ferrule slide over the pipe and, as the nut tightens, the ferrule compresses against the fitting to seal. Glue, solder, or tape aren’t used to make reliable PEX joints, and threaded/tape methods are typical of metal or PVC piping rather than PEX. So compression and crimp are the standard ways to join PEX fittings.
