Asc Engineered Solutions 3.BMCAP Pipe Cap 3 Inch Fnpt

Product Description

The ASC Engineered Solutions 3.BMCAP is a 3-inch malleable iron pipe cap with a female NPT (FNPT) connection, rated for 150 lb service. It is used to seal the end of a threaded pipe run, stopping flow and capping off unused outlets in piping systems. The black finish is standard for gas and industrial piping applications. Plumbers, pipefitters, and gas service technicians install this fitting during system assembly, pressure testing, and service isolation. The domestic manufacture supports code-compliance requirements on jobs that specify American-made materials.

This pipe cap is suited for residential and light commercial piping systems where a 3-inch threaded termination point needs to be closed off. Common applications include natural gas distribution piping, steam systems, and low-pressure water lines. It is installed on Schedule 40 or Schedule 80 threaded pipe ends wherever a permanent or serviceable cap is required.

Key Features

• 3-inch FNPT connection threads directly onto male-threaded pipe ends
• 150 lb pressure class suits gas, steam, and water service
• Malleable iron construction provides strength and resistance to impact and vibration
• Black finish is standard for gas piping and industrial applications

Compatibility

Designed as an OEM-style threaded fitting for use with standard 3-inch male NPT threaded pipe in 150 lb malleable iron piping systems.

Installation Notes

Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system before installing or removing any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before threading on the cap. Ensure the fitting is tightened to a leak-free connection and pressure-tested per applicable code requirements such as the IFGC or IPC before returning the system to service.
