Value Collection MDG220 8 Malleable Iron Pipe Coupling 1/4 in

Product Description

The VALUE COLLECTION MDG220 8 is a Class 150 malleable iron pipe coupling designed for threaded pipe connections in liquid, gas, and steam service. Rated at 300 psi for liquid and gas and 150 psi for steam, it handles the pressure demands common in commercial and light industrial piping systems. The galvanized finish provides corrosion resistance in wet or humid environments. With a 1/4 inch fitting size and standard threaded end connections, this coupling is a straightforward, code-recognized solution for plumbers and pipefitters working on pressurized distribution lines.

This coupling is suited for residential and commercial plumbing, HVAC hydronic systems, compressed air lines, and gas distribution piping where a 1/4 inch threaded malleable iron fitting is required. Its FM Approved and cULus Listed certifications make it appropriate for use in installations that require listed components under fire protection or electrical safety codes. The ISO 7/1 threading standard ensures compatibility with standard taper pipe threads used across North American and international applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with the applicable mechanical and plumbing codes, including the IPC and IFGC where gas service is involved. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not overtighten, as malleable iron fittings can crack under excessive torque.
