Asc Engineered Solutions 1DX1.NMC Reducing Coupling 150 Lb

Product Description

The ASC Engineered Solutions 1DX1.NMC is a galvanized malleable iron pipe reducing coupling rated at 150 lb, designed to connect pipes of two different nominal diameters in a threaded piping system. Sized at 1-1/2 x 1 inch nominal with female NPT (FNPT) ends on both sides, it allows a smooth transition from a larger pipe run to a smaller one without additional fittings. Domestic manufacture supports consistent dimensional tolerances. Licensed plumbers and pipefitters install this fitting in gas, water, and industrial piping systems where reducing connections are needed within standard Class 150 threaded service.

This reducing coupling is suited for residential and light commercial plumbing, gas distribution, and general industrial piping applications. The 1-1/2 inch inlet threads onto the larger pipe or fitting, while the 1-inch outlet connects to the smaller downstream pipe. The galvanized finish provides corrosion resistance in moderate-exposure environments. It is appropriate for use in above-ground and indoor threaded piping systems operating within Class 150 pressure ratings.

Key Features

• Reduces from 1-1/2 inch nominal to 1 inch nominal in a single fitting
• Female NPT (FNPT) threads on both ends for standard threaded pipe connections
• Class 150 lb pressure rating for general-service piping applications
• Galvanized malleable iron construction for corrosion resistance and durability
• Domestically manufactured for consistent dimensional quality

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 150 malleable iron threaded piping systems using 1-1/2 inch and 1 inch nominal pipe sizes with NPT threading.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing and mechanical codes such as the IPC or IFGC. Shut off and depressurize the piping system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly, and tighten to a snug fit using a pipe wrench without over-torquing the malleable iron body. Inspect threads for damage before installation to ensure a leak-free joint.
