The BMI USA 35512 is a 4-inch malleable iron pipe cap with a black finish, used to seal the open end of a threaded pipe. It threads directly onto male pipe threads to close off a line, protect threads during storage, or terminate a piping run permanently. Malleable iron construction provides reliable strength and durability in standard plumbing and mechanical piping applications. Licensed plumbers and pipefitters are the typical installers for this type of fitting in commercial and residential systems.
This pipe cap is suited for use in low-pressure piping systems where a threaded termination is required. It fits 4-inch threaded pipe and is commonly installed in plumbing, gas distribution, and mechanical piping systems where a durable iron cap is specified. The black finish is standard for malleable iron fittings used in gas and general service piping.
Designed as an OEM-style replacement fitting compatible with standard 4-inch threaded malleable iron piping systems in plumbing and mechanical applications.
Installation is performed by a licensed plumber or pipefitter. Shut off all pressure to the line before installing or removing any pipe cap. Apply appropriate thread sealant or PTFE tape to male pipe threads before threading on the cap. Follow applicable local codes and IFGC or IPC standards for the piping system in service.
