Merit Brass MB14170 3/4x1/2 Copper Press Reducing Tee

Product Description

The MERIT BRASS MB14170 is a copper reducing tee designed for push-to-connect press fitting installations in residential and commercial plumbing systems. It transitions a 3/4-inch run to a 1/2-inch branch without soldering, threading, or open flame. Rated to 300 psi maximum working pressure and a maximum working temperature of 250 degrees F, this fitting suits hot and cold water distribution lines. It is lead-free and meets IAPMO PS117 and NSF-61/372 standards, making it suitable for potable water applications. Licensed plumbers and pipefitters install this type of fitting where fast, flame-free connections are required.

The MB14170 is appropriate for residential water supply lines, light commercial plumbing, and hydronic distribution systems where a run-size reduction at a branch point is needed. The press-style end connection eliminates the need for solder, flux, or open flame, making it well suited for retrofit work in occupied spaces or areas with fire restrictions. It is rated for temperatures as low as 0 degrees F, extending its use to systems in unconditioned spaces.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Shut off the water supply and relieve system pressure completely before cutting into any existing line. Ensure pipe ends are cut square, deburred, and clean before inserting into the press fitting. Follow the press tool and jaw manufacturer guidelines for the correct jaw profile when crimping this fitting type.
