The ASC ENGINEERED SOLUTIONS 8700132478 is a 3-inch black pipe cap rated at 150 PSI for use in threaded piping systems. This fitting threads onto the end of an open pipe to seal it, block flow, or cap off a branch that is not yet in service. It is a standard malleable iron or steel fitting used in gas, air, and general-purpose liquid piping systems. Plumbers, pipefitters, and HVAC technicians install this type of cap during rough-in, system testing, and maintenance work where a threaded end must be temporarily or permanently closed.
This 3-inch black pipe cap is suited for residential and light commercial piping applications. It is commonly installed on gas distribution lines, compressed air systems, and hydronic heating piping where a threaded terminal seal is required. The black finish is standard for gas piping in many jurisdictions. Domestic production supports projects that require domestically manufactured fittings under Buy American or prevailing project specifications.
Designed as an OEM-style replacement and standard stocking fitting for 3-inch NPT threaded pipe systems in residential and commercial gas, air, and hydronic piping applications.
This fitting is installed by a licensed plumber or pipefitter using a pipe wrench and appropriate thread sealant or PTFE tape rated for the service media. Always depressurize and isolate the piping system before removing or installing any threaded fitting. Follow local mechanical codes, IFGC requirements for gas piping, and IPC guidelines for plumbing applications. Do not overtighten, as this can crack fittings or damage threads.
