Merit Brass MB14140 Copper Press Tee 3/4 Inch

Product Description

The MERIT BRASS MB14140 is a 3/4 inch copper press tee designed for push-to-connect installation in residential and commercial plumbing systems. This lead-free fitting uses a press-style end connection, eliminating the need for open-flame soldering during installation. It handles up to 300 psi working pressure and operates across a temperature range of 0 degrees F to 250 degrees F, making it suitable for both domestic hot and cold water distribution. Licensed plumbers and mechanical contractors install this fitting as part of copper piping assemblies where speed and code compliance are priorities.

The MB14140 is used in residential and light commercial plumbing installations where 3/4 inch copper branch connections are required. Its push-to-connect press fitting design is well-suited for tight spaces or retrofit work where torch access is limited or restricted by code.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before making or breaking any connections. A manufacturer-specified press tool is required to properly seat press-style fittings — do not substitute with standard compression tools. Verify pipe ends are clean, deburred, and fully inserted to the depth mark before pressing.
