Asc E.NMCAP 3/4 in Fnpt Pipe Cap 150 Lb Galvanized Malleable Iron

Product Description

The ASC Engineered Solutions E.NMCAP is a 3/4 inch straight pipe cap with a female NPT (FNPT) thread pattern, rated for 150 lb service. Constructed from galvanized malleable iron, it is domestically manufactured and designed to seal the open end of a threaded pipe run. The galvanized finish provides corrosion resistance for both indoor and outdoor installations. Plumbers and pipefitters use this cap to terminate gas, water, or air lines in residential and commercial piping systems. Its malleable iron construction offers greater ductility than standard cast iron, making it suitable for installations where minor joint movement or vibration may occur.

This pipe cap is suited for residential and light commercial plumbing, gas distribution, compressed air, and general-purpose pipe systems. It threads directly onto a 3/4 inch male NPT pipe end to provide a clean, pressure-rated termination. Typical applications include capping unused branch outlets, closing off test ports, and terminating future-use stubs in rough plumbing work. Licensed plumbers and pipefitters are the primary installers in both new construction and retrofit projects.

Key Features

• 3/4 inch FNPT thread for direct installation onto standard male NPT pipe ends
• 150 lb pressure rating suitable for general-service pipe systems
• Malleable iron construction provides ductility and resistance to cracking under stress
• Galvanized finish delivers corrosion protection for exposed or damp environments
• Domestically manufactured to Ward Mfg standards

Compatibility

Designed as an OEM-style replacement or standard fitting for 3/4 inch male NPT threaded pipe ends in 150 lb-rated malleable iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the pipe system completely before threading on the cap. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Do not over-torque, as malleable iron fittings can crack if excessive force is applied.
