Asc Engineered Solutions 1BX1.NMC Reducing Coupling 150 Lb

Product Description

The ASC Engineered Solutions 1BX1.NMC is a malleable iron pipe reducing coupling rated at 150 lb, designed to connect pipes of two different diameters within a threaded piping system. It transitions from a 1-1/4 inch nominal pipe to a 1 inch nominal pipe using female National Pipe Taper (FNPT) threads on both ends. The galvanized finish provides corrosion resistance, making it suitable for wet or exposed environments. This fitting is domestically manufactured and is a standard choice for plumbing, gas distribution, and mechanical piping applications where a threaded, reducible connection is required.

This reducing coupling is used in residential and commercial piping systems where pipe size must be stepped down along a run. Typical applications include gas supply lines, water distribution, and general mechanical systems using threaded malleable iron fittings. The 150 lb pressure class fits most standard low-pressure service conditions. Plumbers and pipefitters install this fitting during new construction and retrofit projects where pipe diameter changes are needed at a joint.

Key Features

• Reduces from 1-1/4 inch nominal to 1 inch nominal pipe size
• FNPT threads on both ends for standard threaded pipe connections
• 150 lb pressure rating suitable for standard service conditions
• Malleable iron construction for strength and machinability
• Galvanized finish for corrosion resistance in wet or exposed installations
• Domestically manufactured

Compatibility

Designed as an OEM-style replacement or new-install fitting for standard 150 lb malleable iron threaded piping systems using 1-1/4 inch and 1 inch nominal pipe sizes with FNPT connections.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable code requirements such as the International Plumbing Code (IPC) or International Fuel Gas Code (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 making up the joint. Do not over-tighten, as malleable iron threads can crack under excessive force.
