Value Collection MDB240 50X40-2 Reducing Coupling 2x1.5in

Product Description

The VALUE COLLECTION MDB240 50X40-2 is a black malleable iron reducing coupling designed to connect pipe sections of two different diameters in threaded piping systems. It transitions from a 2-inch pipe to a 1-1/2-inch pipe and uses threaded connections on both ends for secure, leak-resistant joints. Rated at Class 150, this coupling is built for low-pressure gas, water, and general-purpose piping applications. The black finish is standard for gas-service fittings and provides basic corrosion resistance. Licensed plumbers and pipefitters install this fitting in both residential and light commercial systems.

This reducing coupling is suited for threaded malleable iron piping systems in residential and commercial plumbing, gas distribution, and mechanical piping. The 2-inch by 1-1/2-inch size handles common reduction scenarios found in supply branches, fixture connections, and equipment tie-ins. It meets Enterprise Standard, GB/T 7306.2, and ISO 7/1 specifications, making it appropriate for systems requiring verified dimensional and thread-form compliance. Sold in a package of 2 pieces.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off all gas or water supply and depressurize the line before removing or installing any threaded fitting. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-torque the fitting, as malleable iron threads can crack under excessive force.
