Value Collection MDB240 40X25-2 Reducing Coupling 1-1/2x1

Product Description

The VALUE COLLECTION MDB240 40X25-2 is a black malleable iron reducing coupling designed for threaded pipe assemblies in plumbing, gas, and industrial piping systems. It transitions a 1-1/2 inch pipe down to a 1 inch pipe and is rated to 1,500 psi, making it suitable for demanding liquid and gas service. The black finish is standard for gas piping applications. Built to Class 300 and Schedule 80 specifications, this coupling meets Enterprise Standard, GB/T 7306.2, and ISO 7/1 requirements. Licensed plumbers and pipefitters are the typical installers for this type of fitting.

This reducing coupling is used in residential and commercial piping installations where a threaded diameter reduction is required along a run of black iron pipe. Common applications include natural gas distribution lines, steam systems, compressed air lines, and industrial fluid piping. The threaded end connections allow for tool-only makeup without welding or soldering, simplifying installation in retrofit and new-construction scenarios alike.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded black iron pipe systems requiring a 1-1/2 inch to 1 inch reducing coupling in Class 300 and Schedule 80 service.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and IFGC or IPC requirements. Shut off and depressurize the supply line fully before disassembling or threading any fittings. Apply an approved pipe thread sealant or PTFE tape to the male threads before makeup. Do not over-tighten; use a pipe wrench and backup wrench to avoid stressing adjacent fittings or pipe.
