The BMI USA 35502 is a 1/4 inch malleable iron pipe cap with a black finish, used to seal the end of a threaded pipe. Pipe caps thread onto the male end of a pipe to close off a line, prevent contamination, and maintain system pressure during pressure testing or when a branch is temporarily or permanently taken out of service. At 0.05 pounds, this lightweight fitting is easy to handle and is a standard component in residential and commercial piping rough-in and service work.
This pipe cap is suited for use in gas, plumbing, and mechanical piping systems where a threaded end closure is required. It is commonly installed by licensed plumbers and pipefitters during new construction, renovation, or system repairs. The black malleable iron construction makes it appropriate for gas distribution and black iron piping systems in both residential and light commercial applications.
Designed as an OEM-style replacement and standard fitting for 1/4 inch male-threaded black iron pipe systems in gas and mechanical piping applications.
Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the supply line before installing or removing any pipe cap. Apply an appropriate thread sealant or PTFE tape to the male threads before threading the cap on by hand, then tighten with a pipe wrench to the fitting manufacturer recommendations. Follow all applicable local plumbing and gas codes, including IFGC and IPC requirements, when using this fitting in a gas or water piping system.
