Asc Engineered Solutions 2X1B.NMC Reducing Coupling 150 Lb

Product Description

The ASC ENGINEERED SOLUTIONS 2X1B.NMC is a malleable iron pipe reducing coupling rated at 150 lb, designed to transition between a 2-inch nominal pipe and a 1-1/4-inch nominal pipe within a threaded piping system. Both ends feature female National Pipe Taper (FNPT) threads for secure, leak-resistant connections. A galvanized finish provides corrosion resistance in wet or exposed environments. This fitting is domestically manufactured and is installed by licensed plumbers and pipefitters working on gas distribution, water supply, or industrial piping systems.

This reducing coupling is used in residential and commercial piping applications where a threaded line must step down in diameter. Typical scenarios include branch supply lines, equipment connections, and service drops where flow is directed from a 2-inch main to a 1-1/4-inch run. The galvanized malleable iron construction makes it suitable for above-ground gas piping, compressed air systems, and general-purpose water lines where moderate pressure and mechanical durability are required.

Key Features

• Reduces from 2-inch nominal to 1-1/4-inch nominal in a single fitting
• FNPT threads on both ends for standard threaded pipe assembly
• 150 lb pressure rating suitable for low- to moderate-pressure systems
• Malleable iron construction resists cracking and handles mechanical stress better than cast iron
• Galvanized finish provides corrosion protection in wet or outdoor-exposed installations
• Domestically manufactured to support supply chain traceability requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 150 lb malleable iron threaded piping systems using 2-inch and 1-1/4-inch nominal pipe sizes per ASME B16.3 standards.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters. Shut off and depressurize the line completely before removing any existing fitting or making new connections. Apply appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten using a properly sized pipe wrench. On gas piping systems, all work must conform to the International Fuel Gas Code (IFGC) and applicable local codes.
