The BMI USA 35573 is a malleable iron black pipe tee designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. With a 2.5 x 2.5 x 1 inch configuration, it provides a branch outlet off a main run, allowing flow to be divided or redirected within the system. The black finish is standard for gas piping applications. At 2.93 pounds, this fitting is built for durable service in both new construction and retrofit work. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
This tee fitting is used in residential and commercial threaded pipe systems where a branch connection is required on a 2.5 inch main line with a 1 inch branch outlet. Common applications include gas supply lines, steam systems, compressed air distribution, and black iron plumbing assemblies. It is suited for above-ground installations where malleable iron fittings meet code and job-spec requirements.
Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded black iron pipe systems in plumbing, gas, and mechanical applications.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code or International Plumbing Code where relevant. Shut off gas or fluid supply and relieve system pressure before working on any threaded pipe assembly. Apply pipe thread sealant rated for the intended service medium to all male threads before assembly. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque from power tools.
