The BMI USA 20505 is a 3/4-inch extra heavy (XH) black pipe cap made from malleable iron. Pipe caps are used to close off the end of a threaded pipe run, isolating a section of piping from flow or pressure. This cap is finished in black, indicating an extra heavy wall rating suitable for higher-pressure applications. It is installed by licensed plumbers and pipefitters working on gas, steam, water, or industrial piping systems that require a durable threaded closure. The malleable iron construction provides reliable strength and thread engagement under demanding service conditions.
This cap is suited for residential and light commercial piping applications where a 3/4-inch threaded end closure is needed. Common installation scenarios include capping unused branch outlets, isolating sections of gas distribution piping, and closing off pipe ends during pressure testing or system modifications. The black finish is standard for gas service and higher-pressure piping systems.
Designed as an OEM-style replacement or direct-install pipe cap for 3/4-inch threaded pipe systems requiring an extra heavy malleable iron closure.
Installation is performed by licensed plumbers or pipefitters. Depressurize and isolate the pipe section before installing or removing any threaded cap. Apply appropriate thread sealant or tape per local code and the applicable piping standard before threading the cap onto the pipe. Follow IFGC or IPC requirements as applicable to the system type being serviced.
