Asc Engineered Solutions 1XD.NMC Reducing Coupling 1x1/2 in

Product Description

The ASC Engineered Solutions 1XD.NMC is a malleable iron pipe reducing coupling rated at 150 lb, designed to connect a 1-inch pipe to a 1/2-inch pipe using female NPT (FNPT) threads on both ends. The galvanized finish provides corrosion resistance suited for general-purpose piping systems. This coupling is a domestically manufactured fitting commonly installed by licensed plumbers and pipefitters in low-pressure gas, water, and steam distribution lines where a threaded pipe size reduction is required.

This reducing coupling is used in residential and light commercial plumbing and gas piping systems where a transition between 1-inch and 1/2-inch threaded pipe is needed. Typical applications include branch line reductions, boiler piping, natural gas distribution, and compressed air systems operating within the 150 lb pressure class. It is suitable for use with black iron or galvanized pipe and is compliant with standard malleable iron fitting practices for threaded systems.

Key Features

• Reduces 1-inch nominal pipe to 1/2-inch nominal in a single inline fitting
• FNPT threading on both ends for standard threaded pipe connection
• 150 lb pressure class rating for low-pressure gas, water, and steam service
• Malleable iron construction offers strength and impact resistance
• Galvanized finish for added corrosion protection
• Domestically manufactured to standard malleable iron fitting dimensions

Compatibility

Designed as an OEM-style threaded reducing coupling for use with standard 1-inch and 1/2-inch NPT threaded pipe in 150 lb malleable iron piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where relevant. Shut off and depressurize the line fully before disassembling any existing fittings or making new connections. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-torque the fitting, as malleable iron threads can crack under excessive force.
