Asc Engineered Solutions 1D.BMCAP Pipe Cap 1-1/2 in Fnpt 150 Lb

Product Description

The ASC ENGINEERED SOLUTIONS 1D.BMCAP is a 1-1/2 inch FNPT malleable iron pipe cap rated at 150 lb, designed to terminate open pipe ends in low-pressure gas, air, water, and steam distribution systems. The black finish indicates suitability for gas service applications. Manufactured domestically, this threaded cap meets standard dimensional requirements for use in commercial and residential piping assemblies. It is installed by licensed plumbers, pipefitters, and HVAC technicians as part of routine pipe system construction, pressure testing, or future service point capping.

This pipe cap is used in residential and light commercial piping systems where a threaded termination is required. Typical applications include capping gas branch lines, isolating unused ports on manifolds, and blanking off test points after pressure verification. The FNPT (female national pipe taper) thread pattern provides a standard tapered thread engagement compatible with NPT male pipe ends. Domestic manufacture supports project specifications that require USA-made fittings.

Key Features

• 1-1/2 inch FNPT thread accepts standard NPT male pipe ends
• 150 lb pressure class rated for low-pressure gas, air, water, and steam service
• Malleable iron construction provides strength and resistance to impact compared to cast iron
• Black finish suitable for gas piping applications
• Domestically manufactured for projects requiring USA-origin fittings

Compatibility

Designed as an OEM-style replacement or new-install fitting compatible with 1-1/2 inch NPT male threaded pipe ends in standard 150 lb malleable iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC). Shut off and depressurize the system fully before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape rated for the intended service medium before threading the cap onto the pipe. Hand-tighten first, then wrench-tighten to achieve a leak-free seal without over-stressing the fitting threads.
