The BMI USA 35614 is a 6-inch malleable iron pipe plug finished in black, designed to seal the open ends of threaded pipe fittings in plumbing, HVAC, and industrial piping systems. This plug provides a secure, pressure-rated closure on pipe ends during pressure testing, system shutdown, or permanent capping of unused branch connections. Weighing 6.57 pounds, the solid malleable iron construction delivers the durability and thread integrity required in demanding trade applications. Licensed plumbers and pipefitters are the primary installers of this type of fitting.
This pipe plug is suited for residential and commercial applications where a robust threaded closure is needed on ferrous piping systems. Typical uses include capping unused tee outlets, sealing pipe ends during hydrostatic pressure tests, and permanently closing off decommissioned branch lines. The black finish is standard for malleable iron fittings used in gas and water distribution piping.
Designed as an OEM-style threaded pipe plug for use with standard 6-inch threaded ferrous pipe fittings in plumbing and industrial piping applications.
Installation should be performed by a licensed plumber or pipefitter following applicable IPC and IFGC code requirements. Depressurize and isolate the pipe section before installing or removing any threaded plug. Apply appropriate thread sealant or PTFE tape to the male threads before installation to ensure a leak-free seal. Do not overtighten, as excessive torque can crack cast fittings or damage mating threads.
