Value Collection B-UNI15 Black Malleable Iron Union 1-1/2 in

Product Description

The VALUE COLLECTION B-UNI15 is a 1-1/2 inch black malleable iron union rated for Class 150 service. It is designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems where a serviceable break-apart connection is required. With a pressure rating of 300 psi, this union handles both liquid and gas service in typical commercial and residential applications. The black finish is standard for gas piping installations. Plumbers, pipefitters, and HVAC technicians install this fitting when a section of pipe must be disconnected for service without cutting the line.

This union is suited for low-pressure gas distribution lines, hydronic heating systems, compressed air drops, and general black iron pipe assemblies. The 1-1/2 inch threaded end connections conform to standard NPT thread patterns used throughout residential and light commercial construction. It is appropriate for applications where periodic disconnection and reconnection of a pipe run is anticipated, such as at equipment connections or service isolation points.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the gas or fluid system completely before disassembling or installing any union fitting. Apply appropriate pipe thread sealant or tape rated for the service fluid to all male threads before assembly. Tighten the union nut by hand first, then snug with a pipe wrench, taking care not to over-stress the fitting body.
