Asc Engineered Solutions E.NMC 3/4 in Pipe Coupling Fnpt 150 Lb

Product Description

The ASC Engineered Solutions E.NMC is a 3/4-inch nominal straight pipe coupling designed for threaded pipe assemblies in plumbing, gas, and mechanical systems. Built from malleable iron with a galvanized finish, it accepts female NPT (FNPT) connections on both ends and carries a 150 lb pressure class rating. The galvanized coating provides corrosion resistance suitable for exposed or damp installations. This coupling is a domestically produced fitting intended for installation by licensed plumbers, pipefitters, and mechanical contractors working on low-pressure pipe runs.

This coupling is used in residential and light commercial piping applications where a straight inline connection between two threaded pipe sections is needed. Common install scenarios include gas distribution lines, water supply headers, compressed air drops, and general mechanical piping. The 3/4-inch nominal size is one of the most common thread sizes across these systems, making this fitting a standard stocking item for service trucks and shop inventory alike.

Key Features

• 3/4-inch nominal FNPT threading on both ends for standard NPT pipe
• 150 lb pressure class malleable iron construction
• Galvanized finish for corrosion resistance in damp or exposed environments
• Straight coupling profile for inline pipe-to-pipe connections
• Domestically manufactured to standard pipe fitting dimensions

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded pipe systems using standard 150 lb malleable iron fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Shut off and depressurize the pipe system completely before threading or unthreading any fittings. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten, as malleable iron fittings can crack under excessive torque.
