B K Mueller 520-765HC Black Reducing Tee 1.25x1 in 5 Pack

Product Description

The B K Mueller Industries 520-765HC is a black reducing tee fitting designed for threaded pipe assemblies in gas, air, and general-purpose piping systems. This fitting reduces from a 1.25-inch run to a 1-inch branch, allowing directional splits or service connections in a single component. Black pipe fittings of this type are standard in low-pressure gas distribution, compressed air lines, and industrial fluid conveyance. Each unit ships as part of a 5-piece package with a combined package weight of 5.77 pounds. Licensed plumbers, pipefitters, and HVAC technicians are the typical installers for this class of fitting.

This reducing tee is suited for residential and light commercial applications where threaded black iron pipe systems are required. Common install scenarios include natural gas supply lines, propane distribution headers, and shop air systems with mixed pipe diameters. The 1.25-inch inlet to 1-inch outlet reduction is a frequently specified size transition in both new construction and retrofit work. The package quantity of 5 makes this SKU practical for contractors stocking a service van or completing multi-drop installations.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes including the IFGC for gas service applications. Shut off and depressurize the supply line completely before cutting into an existing system or removing any existing fitting. Apply an appropriate thread sealant or tape rated for the intended service medium before making up the joint. Do not over-tighten threaded connections, as this can crack the fitting body or damage threads.
