The BMI USA 35575 is a malleable iron black tee fitting used in threaded pipe assemblies for gas, air, and compatible fluid distribution systems. This tee connects a 2.5-inch run with a 2.5-inch outlet and a 0.5-inch branch port, allowing a directional split in the piping line. Weighing 2.63 pounds, it is built from malleable iron and finished in black, giving it the corrosion-resistance profile expected in industrial and commercial plumbing and gas piping work. Plumbers, pipefitters, and gas technicians are the primary installers of this fitting type.
This tee is suited for residential and light commercial threaded pipe systems where a reducing branch connection is required. Typical applications include gas distribution piping, compressed air lines, and steam or water systems that call for a threaded malleable iron fitting at those dimensions. Its black finish distinguishes it from galvanized fittings and is standard in gas line installations where code permits.
Designed as an OEM-style replacement or direct installation fitting for threaded malleable iron pipe systems using standard NPT connections.
Installation should be performed by a licensed plumber, pipefitter, or gas technician in accordance with applicable local codes and IFGC or IPC requirements. Shut off gas or fluid supply and depressurize the line fully before disassembling any existing fittings. Apply an approved thread sealant or PTFE tape to all male threads before making up the joint. Do not over-tighten threaded connections in malleable iron fittings, as this can crack the casting.
