The BMI USA 20506 is an extra heavy malleable iron pipe cap finished in black, designed to seal the end of a pipe in plumbing, gas, steam, or industrial piping systems. This threaded cap screws onto the male end of a pipe to close off flow, protect threads during storage or transport, or permanently cap an unused line. At 0.57 pounds and rated as extra heavy, it is built for demanding applications where a standard-weight fitting would not provide adequate strength or durability. Licensed plumbers and pipefitters are the primary installers for this type of fitting.
This cap is suited for residential and commercial piping installations where an extra heavy threaded end cap is required on a 1-inch pipe. Common applications include gas distribution lines, steam piping, industrial process lines, and general plumbing rough-in work. The black finish is typical for gas and steam service fittings and distinguishes extra heavy fittings from standard galvanized or black standard-weight products.
Designed as an OEM-style threaded pipe cap for use on 1-inch male NPT pipe ends in standard black malleable iron piping systems.
This fitting is installed by a licensed plumber or pipefitter using appropriate pipe wrenches and thread sealant or PTFE tape on all threaded connections. Shut off and depressurize the line completely before removing or capping any fitting. Follow all applicable codes including the International Fuel Gas Code (IFGC) for gas piping applications and the International Plumbing Code (IPC) for water and drain systems. Do not overtighten malleable iron fittings, as excessive force can crack the casting.
