The BMI USA 20404 is an extra heavy black malleable iron pipe tee designed for threaded pipe assemblies in demanding plumbing, gas, and mechanical piping systems. Constructed from extra heavy malleable iron with a black finish, this tee provides a branch connection in a straight pipe run and is built to handle higher-pressure applications where standard-weight fittings are not sufficient. Licensed plumbers and pipefitters install this fitting as part of threaded black iron piping systems. Weighing 0.66 pounds, the 1/2 inch tee offers solid construction suited to both residential and light commercial installations.
This fitting is commonly used in gas distribution piping, steam systems, fire protection rough-in, and general industrial pipe assemblies where extra heavy wall thickness is required. The black finish is standard for natural gas and propane supply lines as well as steam and air piping applications. It is appropriate for interior rough-in work where a threaded branch connection is needed off a main pipe run.
Designed as an OEM-style replacement or standard fitting for extra heavy threaded black iron pipe systems in residential and commercial plumbing, gas, and mechanical piping applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off gas or fluid supply and relieve system pressure before making or breaking any threaded connections. Apply appropriate thread sealant or PTFE tape to all NPT threads before assembly. Do not over-tighten threaded fittings, as malleable iron can crack under excessive torque.
