Value Collection G-UNI15 Malleable Iron Pipe Union 1-1/2 in

Product Description

The VALUE COLLECTION G-UNI15 is a 1-1/2 inch malleable iron pipe union rated for 300 psi on liquid and gas service and 150 psi on steam service. It carries a Class 150 designation and features a galvanized finish coating for corrosion resistance. The union design allows two sections of threaded pipe to be connected or disconnected without rotating the pipe itself, making it a standard component in plumbing, piping, and mechanical systems. Plumbers, pipefitters, and mechanical contractors install this fitting wherever a breakout point is needed in a threaded iron pipe run.

This union is suited for residential and commercial applications involving gas distribution lines, water supply piping, steam systems, and general industrial fluid piping. The galvanized finish makes it appropriate for environments with moderate moisture exposure. It is installed in threaded pipe systems where routine service access or future disconnection of a pipe section is anticipated. The 1-1/2 inch size is common in branch and main supply runs in both new construction and retrofit work.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC requirements depending on the service media. Shut off all fluid or gas supply and depressurize the line completely before disassembling or installing any union fitting. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Hand-tighten the union nut first, then bring to final tightness with a pipe wrench, being careful not to overtighten malleable iron fittings.
