Merit Brass MB14190 Press Tee 1 Inch Fitting

Product Description

The MERIT BRASS MB14190 is a 1-inch press tee fitting designed for use in copper press piping systems. It connects three sections of pipe at a tee junction without the need for open-flame soldering or brazing. The press connection method uses a press tool to create a secure, leak-tight joint in seconds, making it a reliable choice for plumbing and hydronic heating installations. At 0.4 pounds, it is lightweight and easy to handle during installation. Licensed plumbers and pipefitters working on residential and light commercial systems are the primary installers of this fitting.

The MB14190 press tee is suited for residential and light commercial plumbing, hydronic heating, and radiant systems where copper press technology is preferred over soldered joints. It is commonly used in areas where open flame is restricted or where faster installation times are required, such as occupied buildings, retrofit projects, and mechanical rooms with limited access.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASTM standards for copper press systems. Shut off and depressurize the water supply and drain the line before cutting into an existing system. Use a press tool with the correct 1-inch jaw profile rated for this fitting type. Verify the pipe end is clean, deburred, and fully inserted to the depth mark before pressing.
