Asc Engineered Solutions 1D.NMC Pipe Coupling 1-1/2 in Fnpt

Product Description

The ASC Engineered Solutions 1D.NMC is a straight pipe coupling rated at 150 lb, manufactured from galvanized malleable iron for durability in demanding piping systems. It features female National Pipe Thread (FNPT) ends on both sides and accepts 1-1/2 inch nominal pipe. The galvanized finish provides corrosion resistance in wet or exposed environments. This fitting is domestically manufactured and is used by licensed plumbers and pipefitters to join two sections of threaded pipe in a straight run. Its malleable iron construction handles the mechanical stress common in commercial and industrial piping without cracking under impact.

This coupling is suited for use in residential and commercial plumbing, fire protection, and general industrial piping systems where threaded malleable iron fittings are specified. It is commonly installed in water distribution lines, compressed air systems, and hydronic heating piping. The 1-1/2 inch nominal size makes it a standard choice in medium-diameter pipe runs where a full-thread inline connection is needed. Installers working on gas piping should verify local code approval for gas service applications before use.

Key Features

• 1-1/2 inch nominal pipe size with FNPT ends on both sides for standard threaded connections
• 150 lb pressure class malleable iron construction handles typical commercial piping loads
• Galvanized finish resists corrosion in wet, exposed, or outdoor environments
• Domestically manufactured to standard pipe fitting dimensions
• Straight coupling design joins two pipe sections in a continuous inline run

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/2 inch nominal threaded pipe systems using standard NPT connections in 150 lb class malleable iron piping assemblies.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the International Plumbing Code (IPC) or local equivalents. Shut off and depressurize the piping system completely before making or breaking any threaded connections. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly and tighten to hand-tight plus wrench-turns per standard practice for NPT fittings. Do not over-tighten, as malleable iron fittings can crack if excessive force is applied.
