The BMI USA 20008 is a 1-1/2 inch Class 300 extra heavy black malleable iron pipe coupling designed for threaded pipe connections in demanding piping systems. Cast from extra heavy malleable iron and finished in black, this coupling provides a robust threaded joint suitable for high-pressure and industrial-grade installations. Licensed plumbers and pipefitters install this fitting where standard-weight couplings are insufficient for the service conditions. At 1.93 pounds, the part carries the mass expected of a Class 300 XH fitting built to last in hard-use environments.
This coupling is appropriate for use in commercial and industrial piping systems that require a Class 300 extra heavy rated threaded fitting. It is commonly installed in steam, gas, air, and water distribution lines where elevated pressure ratings or heavier wall sections are specified by the engineer or code authority. The black finish makes it a standard choice for gas distribution and fire protection piping where galvanized coatings are not required.
Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch threaded pipe systems requiring Class 300 extra heavy malleable iron couplings.
Installation of threaded pipe fittings should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. De-pressurize and isolate the line before making or breaking any threaded connection. Apply listed thread sealant or tape appropriate for the service medium before threading the coupling onto the pipe. Do not over-torque threaded connections, as this can crack the fitting or damage threads.
