Asc Engineered Solutions 1XE.NMC Pipe Reducing Coupling

Product Description

The ASC Engineered Solutions 1XE.NMC is a galvanized malleable iron pipe reducing coupling rated at 150 lb, designed to connect pipes of two different nominal sizes within a threaded piping system. Featuring female NPT (FNPT) threading on both ends, it transitions a 1-inch nominal pipe down to a 3/4-inch nominal pipe. Domestically manufactured, this fitting is built for reliable service in water, gas, and general plumbing distribution systems. Licensed plumbers and pipefitters install this type of fitting during new construction, retrofit work, and repair projects where pipe diameter reductions are required at threaded connections.

This reducing coupling is suited for residential and light commercial piping applications including potable water supply lines, hydronic heating systems, natural gas distribution, and compressed air lines. The galvanized finish provides corrosion resistance for both indoor and outdoor installations. It is a standard Class 150 malleable iron threaded fitting commonly used wherever a step-down in pipe size is needed in a threaded iron pipe system.

Key Features

• Reduces from 1-inch nominal to 3/4-inch nominal in a single fitting
• FNPT threading on both ends for standard threaded pipe connection
• 150 lb pressure class malleable iron construction
• Galvanized finish for corrosion resistance in wet or outdoor environments
• Domestically manufactured to meet standard trade quality expectations

Compatibility

Designed as an OEM-style replacement and standard-use reducing coupling compatible with Class 150 malleable iron threaded pipe systems using 1-inch and 3/4-inch nominal NPT pipe.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter using pipe wrenches and appropriate thread sealant or PTFE tape applied to the male threads mating into this fitting. Shut off and depressurize the pipe system completely before disassembling or installing any threaded fittings. For gas service, consult local codes and the IFGC before installation. Do not overtighten threaded connections, as malleable iron fittings can crack if excessive torque is applied.
