The BMI USA 35432 is a malleable iron black pipe tee used to create branch connections in threaded pipe systems. This fitting connects three pipe segments at a tee junction, with a 3/4-inch run, 1/2-inch branch, and 1-inch outlet configuration. The black finish comes from an oil or lacquer coating applied after casting, standard for malleable iron gas and air distribution fittings. Plumbers, pipefitters, and gas service technicians use this fitting where a reducing branch connection is required on threaded iron pipe systems.
This tee is suited for residential and light commercial piping applications including natural gas distribution, propane lines, compressed air systems, and water supply where black malleable iron fittings are specified. The reducing dimensions make it useful where main line and branch sizes differ, eliminating the need for additional reducers at the junction point.
Designed as an OEM-style replacement or new-installation fitting for threaded black malleable iron pipe systems using NPT threading in residential and commercial gas, air, or fluid piping.
Installation of this fitting should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the supply line before making any threaded connections. Apply appropriate thread sealant or PTFE tape rated for the service media before hand-tightening and wrenching to a secure fit. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
