The BMI USA 35419 is a malleable iron black pipe tee designed for joining threaded pipe runs in plumbing, gas distribution, and mechanical piping systems. With a 1/2 x 1/2 x 1 inch configuration, this tee allows a branch connection off a main run while maintaining a secure, leak-resistant threaded joint. The black finish indicates an uncoated malleable iron fitting suitable for gas and air lines. At 0.49 pounds, it is a compact, durable fitting installed by licensed plumbers, pipefitters, and HVAC technicians working with threaded iron pipe assemblies.
This fitting is appropriate for residential and light commercial applications where threaded black iron pipe is the specified material. Common use cases include natural gas supply lines, compressed air distribution, and steam or hydronic heating rough-in work. The 1/2 x 1/2 x 1 inch sizing makes it well suited for reducing or branching configurations within standard iron pipe systems.
Designed as an OEM-style replacement and standard fitting for use with threaded black iron pipe systems following NPT thread standards in residential and commercial piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off all gas or fluid supply and depressurize the line before removing or installing fittings. Apply an appropriate pipe thread sealant or PTFE tape rated for the intended service medium to all threaded connections. Inspect threads for damage before assembly and do not overtighten, as malleable iron fittings can crack under excessive torque.
