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

Product Description

The ASC Engineered Solutions 1D.NMCAP is a straight pipe cap designed to terminate open-ended pipe runs in low-pressure gas, water, and general plumbing systems. Manufactured from malleable iron with a galvanized finish, this cap threads onto a 1-1/2 inch female NPT (FNPT) connection and is rated for 150 lb service. The galvanized coating provides corrosion resistance suitable for exposed or moderately harsh environments. Licensed plumbers and pipefitters install this fitting during system commissioning, pressure testing, or any time a pipe end requires a permanent or temporary closure. Its domestic manufacture supports project specifications that require USA-made components.

This pipe cap is used in residential and light commercial piping systems including natural gas distribution, potable water supply, hydronic heating, and compressed air lines. It is well suited for capping unused branch tees, isolating sections of pipe during phased construction, or closing off service ports. The FNPT thread pattern allows it to thread directly onto standard NPT male pipe ends without adapters.

Key Features

• 1-1/2 inch FNPT connection threads directly onto standard NPT male pipe ends
• 150 lb pressure-class rating suitable for low- to medium-pressure service
• Malleable iron construction provides strength and impact resistance over cast iron
• Galvanized finish offers corrosion protection for indoor and outdoor installations
• Domestically manufactured for compliance with buy-domestic project specifications

Compatibility

Designed as an OEM-style replacement or standard stock fitting for 1-1/2 inch NPT malleable iron piping systems rated at 150 lb service class.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable code requirements including the IPC and IFGC where gas service is involved. Depressurize and isolate the piping system completely before threading on the cap. Apply thread sealant or PTFE tape appropriate for the service medium to the male pipe threads before installation. Do not over-tighten; use a pipe wrench to achieve a firm, leak-free connection without stressing the fitting.
