Value Collection MSC-62149687 Malleable Iron Union 1/4 in

Product Description

The VALUE COLLECTION MSC-62149687 is a 1/4 inch threaded malleable iron pipe union with a black finish, rated Class 150. Unions allow a pipeline to be assembled and disassembled without disturbing adjacent fittings or pipe runs. This fitting carries a 300 psi liquid and gas pressure rating, making it suitable for low-pressure gas, air, water, and general fluid service lines. Licensed plumbers and pipefitters install this type of union in commercial and industrial piping systems where routine service access or future disconnection is required.

This fitting is suited for residential and light commercial piping applications involving threaded iron pipe systems. Typical installations include gas distribution lines, compressed air headers, water service runs, and hydronic heating systems where a threaded union connection is specified. The black finish is standard for gas piping in many jurisdictions. The 1/4 inch size fits small-diameter branch lines and instrument connections common in trade service work.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the line before disassembling or installing any union fitting. Apply thread sealant or PTFE tape rated for the intended service medium to all threaded connections. Do not overtighten the union nut, as malleable iron threads can be damaged by excessive torque.
