Value Collection MSC-62147962 Malleable Iron Pipe Union 3/4 in

Product Description

The VALUE COLLECTION MSC-62147962 is a 3/4-inch malleable iron pipe union designed for threaded piping systems in plumbing, HVAC, and light industrial applications. It carries a 300 psi pressure rating for liquid and gas service and a 150 psi rating for steam service, placing it in the widely used Class 150 fitting category. The galvanized finish provides corrosion resistance in moderate-duty environments. At 1.5 pounds, this union is a standard-weight fitting suitable for permanent and serviceable pipe connections where routine disassembly is required.

This union is used in residential and commercial piping systems where two sections of threaded pipe must be joined and later separated without cutting. Typical applications include gas distribution lines, water supply runs, and hydronic heating piping. The 3/4-inch size is common in branch lines and secondary supply runs across both new construction and retrofit service work. Licensed plumbers, pipefitters, and HVAC mechanics are the primary installers.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded piping systems in plumbing, gas, and hydronic HVAC applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements for the service type. Shut off and depressurize the piping system completely before disassembling or installing any union fitting. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Tighten the union nut by hand first, then wrench-tighten to achieve a leak-free seal without over-stressing the fitting.
