Value Collection MDG220 40-2 Malleable Iron Pipe Coupling

Product Description

The VALUE COLLECTION MDG220 40-2 is a 1-1/2 inch galvanized malleable iron pipe coupling with right-hand threaded ends, designed for joining sections of threaded pipe in gas and liquid distribution systems. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 coupling is built to handle the pressure demands common in commercial and industrial piping installations. The galvanized finish provides corrosion resistance for extended service life in exposed or moderately harsh environments. Licensed plumbers and pipefitters install this fitting as part of iron pipe assemblies in mechanical rooms, utility lines, and process piping.

This coupling is suited for residential and commercial applications where standard threaded malleable iron fittings are required. Typical uses include natural gas distribution lines, compressed air systems, water supply piping, and steam lines operating within the rated pressure limits. The right-hand thread orientation follows standard NPT conventions used throughout North American pipe systems. The package contains 2 couplings per unit, with a minimum order quantity of 1 package.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing and mechanical codes such as the IPC or IFGC. Shut off and depressurize the pipe system completely before disassembling or installing any fittings. Apply an appropriate thread sealant or PTFE tape to the male threads before making up the joint. Do not overtighten, as malleable iron fittings can crack under excessive torque.
