The SharkBite U4016LF is a polybutylene conversion coupling designed to connect polybutylene pipe to PEX, copper, CPVC, and PE-RT pipes easily. This fitting is lead-free and offers a push-to-connect design for quick installation without the need for special tools, crimping, or soldering.
This coupling facilitates faster installations in tight spaces, and it can be installed while the lines are wet. The fitting features color-coordinated collars for easy identification—gray for polybutylene and tan for other pipe types.
