PEX to PB Fittings

Polybutylene piping was common in the United States for a brief period starting in the 1970’s. The grey plastic tubing is still present in some installations from that time. In the event that polybutylene must be connected to PEX, fittings are available in limited sizes. SharkBite U4008LF and U4016LF fittings transition from PB to a traditional SharkBite fitting.

Keep in mind the standard PEX fittings, crimping tools, and rings do not work with polybutylene piping. For a larger selection of PEX fittings for plumbing visit
