Flair-It PEXLOCK 30874 Swivel Pipe Adapter, 3/8 x 1/2 in, BSPT, Polysulfone, Black, 100 psi Pressure

Until now, the PEX industry has been limited in it's ability to grow because of the need for special expensive tooling required by the metal PEX connection clamps. With the PEXLOCK™ clamp, anyone can plumb with PEX using just a pair of common household pliers. All PEXLOCK™ part numbers come retail bagged fitting plus rings.
