The VALUE COLLECTION MDB240 25X15-5 is a black malleable iron reducing coupling designed for threaded pipe assemblies in plumbing, gas distribution, and mechanical piping systems. It transitions from a 1-inch pipe to a 1/2-inch pipe using tapered threads that conform to GB/T 7306.2 and ISO 7/1 standards. The black finish is applied over malleable iron, providing corrosion resistance suitable for indoor dry or semi-dry installations. Rated at Class 150, this coupling handles standard low-pressure service applications. Licensed plumbers and pipefitters install this fitting as part of branch reductions in residential and light commercial piping runs.
This reducing coupling is suited for residential and light commercial plumbing, gas, and mechanical systems where a pipe size transition from 1 inch down to 1/2 inch is required. It is commonly used in supply lines, branch takeoffs, and fixture connections where threaded malleable iron fittings are specified. The Class 150 pressure rating and compliance with Enterprise Standard, GB/T 7306.2, and ISO 7/1 make it appropriate for standard service piping applications. This item is sold in a package quantity of 5.
Designed as an OEM-style replacement or new-installation fitting for standard threaded malleable iron piping systems requiring a 1-inch to 1/2-inch reducing coupling at Class 150 service pressure.
Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where relevant. Shut off and depressurize the supply line completely before cutting into any existing piping. Apply an approved thread sealant or PTFE tape to the male threads before assembly. Do not over-tighten; use a pipe wrench with a backup wrench to avoid stressing adjacent fittings or pipe.
