Rwc U004LFA Sharkbite Max Straight Brass Coupling 1/4 in

Product Description

The RWC U004LFA is a SharkBite Max push-to-connect straight brass coupling designed for fast, tool-free pipe connections in residential and light commercial plumbing systems. This 1/4-inch (3/8-inch OD) fitting features a redesigned stainless-steel retainer for added strength and durability, and carries a 250 psi pressure rating. The re-engineered body reduces insertion effort and eliminates the need for a PEX tube liner. No soldering, clamps, unions, glue, or special tools are required. Licensed plumbers and experienced installers use this fitting for efficient, code-compliant connections across a wide range of pipe types.

The U004LFA is suited for residential and light commercial water distribution applications where quick, reliable connections are needed. It connects PEX, copper, CPVC, PE-RT, and HDPE pipe without transition fittings or primers. The fitting can be rotated after installation to ease alignment in tight spaces, and it can be removed and reused with a standard SharkBite disconnect tool, making it practical for retrofit work, repairs, and valve replacements in accessible or concealed installations.
