Asc Engineered Solutions 1.NMCAP Pipe Cap 1 in Fnpt 150 Lb

Product Description

The ASC Engineered Solutions 1.NMCAP is a 1-inch straight pipe cap with a female NPT (FNPT) thread connection, rated for 150 lb service. Constructed from malleable iron with a galvanized finish, this cap is built to seal the end of a threaded pipe run in gas, water, air, and general plumbing distribution systems. The galvanized coating provides corrosion resistance in moderately exposed environments. Plumbers, pipefitters, and mechanical contractors install this fitting where a permanent or serviceable pipe termination is needed on a standard NPT-threaded pipe end.

This pipe cap is suited for residential and light commercial piping systems operating within 150 lb pressure class limits. Typical applications include capping unused branch outlets, sealing test ports after pressure testing, and terminating pipe runs during phased construction. The FNPT thread engages directly onto a male-threaded pipe end, making installation straightforward with standard hand tools and pipe thread sealant.

Key Features

• 1-inch FNPT thread for direct engagement on male NPT pipe ends
• 150 lb pressure class rating suitable for standard service piping
• Malleable iron construction provides strength and resistance to impact compared to cast iron
• Galvanized finish for corrosion resistance in wet or mildly corrosive environments
• Domestic manufacture

Compatibility

Designed as an OEM-style replacement and standard fitting for 1-inch male NPT threaded pipe in 150 lb malleable iron piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements. Shut off and depressurize the piping system fully before installing or removing any threaded cap. Apply an approved pipe thread sealant or PTFE tape to the male threads before threading the cap on by hand, then tighten with a pipe wrench to a proper thread engagement. Do not over-torque malleable iron fittings, as the material can crack under excessive force.
