Sharkbite U016LFA4 3/4 Inch Push-to-connect Straight Coupling 4 Pack

Product Description

The SHARKBITE U016LFA4 is a 3/4-inch push-to-connect straight coupling sold in a 4-pack, designed for fast, reliable pipe joining without soldering, clamps, unions, or glue. Internal stainless steel teeth bite down and grip the pipe on insertion, while a specially formulated O-ring compresses to form a pressure-tight seal. Certified for potable water supply and hydronic heating applications, this fitting is a go-to for plumbers and HVAC techs who need a secure, code-compliant connection in residential and light commercial systems.

The U016LFA4 connects copper, CPVC, and PEX pipe in any combination, making it well-suited for repair work and new installations where mixed pipe materials meet at a single joint. It can be rotated after assembly, which is a significant advantage when working in confined spaces or tight wall cavities. A compatible disconnect tool allows the fitting to be removed and reused, making it practical for temporary installations or when valve and fitting changes are needed downstream.

Compatibility

Connects copper, CPVC, and PEX pipe in any combination at 3/4-inch pipe size. Suitable for potable water supply lines and hydronic heating systems.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off the water supply and depressurize the line before cutting into existing piping. Ensure pipe ends are cut square, deburred, and clean before insertion to achieve a proper seal. A compatible SharkBite disconnect tool is required for fitting removal and should not be substituted with other tools, which may damage the collet or O-ring.
