The MERIT BRASS MB14580 is a press tee fitting designed for joining copper or compatible tubing in plumbing and hydronic systems. The fitting connects two run ends and one branch outlet using a press-fit connection method, eliminating the need for open flame soldering at the joint. It is sized at 2 inches by 2 inches by 1/2 inches, making it suitable for reducing branch applications. Licensed plumbers and pipefitters install this type of fitting in residential and light commercial water distribution and heating systems.
This press tee is used in applications where soldering or threading is not practical or permitted. Common install scenarios include tight mechanical rooms, retrofit work in occupied buildings, and in-wall rough-in where flame-free connections are required. The 2 x 2 x 1/2 inch configuration is typical for a main run with a reduced branch takeoff, such as a sensor port, drain, or secondary supply line in a hydronic or domestic water loop.
Designed as an OEM-style replacement or new-installation press tee fitting for compatible 2-inch and 1/2-inch press-fit piping systems. Verify press jaw and fitting system compatibility before installation.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water or hydronic system and drain the affected line before installing the fitting. Use the correct press jaw size and a listed pressing tool rated for the fitting diameter. Inspect the fitting and pipe ends for debris or damage before pressing to ensure a leak-free joint.
