Value Collection MDG220 50 Malleable Iron Pipe Coupling 2 in

Product Description

The VALUE COLLECTION MDG220 50 is a malleable iron threaded pipe coupling designed for joining sections of pipe in pressurized liquid, gas, and steam systems. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting handles the pressure demands common in commercial and industrial piping runs. The threaded end connection follows standard taper thread dimensions, allowing straightforward installation with standard pipe wrenches and thread sealant. Malleable iron construction provides strength and moderate ductility, making it suitable for a wide range of plumbing, mechanical, and light industrial applications.

This coupling is used in residential and commercial piping systems where two pipe ends require a secure, pressure-rated inline connection. Typical applications include gas distribution lines, steam heating distribution, and general liquid service piping. The 2-inch fitting size accommodates standard 2-inch nominal pipe. Sold in a package quantity of two, this coupling suits service techs and pipefitters who need multiple fittings on a single job without ordering large quantities.

Compatibility

Designed as a standard Class 150 malleable iron threaded coupling for use in 2-inch nominal pipe systems rated for liquid, gas, or steam service.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC code requirements for the service type. Shut off and depressurize the piping system fully before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly and tighten with a pipe wrench to achieve a leak-free joint. Do not over-tighten threaded malleable iron fittings, as cracking can result.
