Merit Brass MB33000 Copper Push-to-connect Union 1/2 in

Product Description

The MERIT BRASS MB33000 is a 1/2 inch copper push-to-connect union fitting designed for fast, solder-free connections in residential and light commercial plumbing systems. This press-style union joins two sections of copper pipe without flame or flux, making it a reliable choice for retrofits and new installs alike. The fitting is lead free and rated for a maximum working pressure of 300 psi and temperatures from 0 degrees F to 250 degrees F. With an outside diameter of 0.965 inches, it seats securely in standard 1/2 inch copper line applications. Licensed plumbers and journeymen installers working in tight spaces will find the push-to-connect end connection a practical time-saver.

This union fitting is suited for potable water supply lines, hydronic heating systems, and general copper plumbing runs in residential construction and light commercial work. Its press-fitting design eliminates the need for open flame during installation, making it appropriate for fire-sensitive jobsites or areas where hot-work permits are restricted. The fitting meets IAPMO PS117 and NSF-61/372 standards, confirming suitability for use in drinking water systems.

Installation Notes

Installation is performed by a licensed plumber following local IPC or applicable plumbing code requirements. Shut off and depressurize the water supply before cutting into the existing line. Pipe ends must be cut cleanly and deburred before insertion into the push-to-connect ends to ensure a proper seal. Do not exceed the rated working pressure or temperature limits of the fitting.
