Value Collection MDG130 20-5 Malleable Iron Tee 3/4 in

Product Description

The VALUE COLLECTION MDG130 20-5 is a 3/4 inch malleable iron pipe tee designed for threaded pipe connections in liquid gas and steam distribution systems. Rated at 300 psi for liquid and gas service and 150 psi for steam, this Class 150 fitting meets ISO 7/1 threading standards. The tee configuration allows a branch connection off a main run, making it a standard component in plumbing, HVAC piping, and gas distribution rough-in work. Licensed plumbers and pipefitters typically install this fitting as part of threaded iron pipe assemblies in both residential and light commercial applications.

This tee fitting is suited for use in threaded iron pipe systems carrying liquid, gas, or low-pressure steam. Common install scenarios include gas supply lines, hydronic heating distribution loops, compressed air headers, and steam piping where a branch takeoff is required. The malleable iron construction handles the mechanical stress of threaded assembly and the thermal cycling typical in these systems. This fitting ships in a package quantity of 5 units.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch threaded iron pipe systems in residential and commercial plumbing, gas, and steam piping applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IPC, and IFGC requirements. Shut off the gas or liquid supply and depressurize the line before disassembly or fitting installation. Use an appropriate thread sealant or PTFE tape rated for the service medium when assembling threaded joints. Do not over-tighten threaded connections, as malleable iron fittings can crack under excessive torque.
