The RWC U518LF is a 3/4-inch nominal push-fit brass pipe end cap designed to terminate open pipe ends quickly and without soldering, crimping, or threading. It connects using a push-to-connect mechanism that grips and seals in a single motion, making it a practical solution for capping live or inactive lines during service, repair, or system modification. The lead-free brass construction meets potable water requirements. Plumbers and pipefitters install this fitting in residential and light commercial water supply systems where fast, reliable termination is needed.
This end cap is suited for use on 3/4-inch pipe in domestic water supply, hydronic heating, and general plumbing distribution systems. The push-fit design eliminates the need for a torch, solder, or press tool, which makes it well-suited for tight spaces and retrofit applications. It is commonly used when capping off branch lines, decommissioning a fixture connection, or isolating a section of piping during service work.
Designed as an OEM-style push-fit replacement end cap for 3/4-inch nominal copper, CPVC, and PEX pipe in residential and light commercial plumbing systems.
Installation is performed by licensed plumbers or qualified pipefitters in accordance with local plumbing codes and the IPC. Shut off water supply and depressurize the line before fitting installation. Ensure pipe end is cut square, deburred, and clean before inserting into the push-fit fitting. Do not exceed the pressure and temperature ratings applicable to the fitting and pipe material combination.
