Value Collection B-UNI07 Malleable Iron Union 3/4 in

Product Description

The VALUE COLLECTION B-UNI07 is a 3/4 inch black malleable iron union designed for threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. Rated at Class 150 with a liquid and gas pressure rating of 300 psi, this union allows sections of threaded pipe to be connected and disconnected without rotating the pipe itself. The black finish is standard for gas and air applications. Weighing 1.4 pounds, it is sized for typical residential and light commercial installations where a removable, pressure-rated threaded connection is required. Licensed plumbers and pipefitters are the primary installers of this fitting.

This union is suited for use in gas distribution lines, steam and water supply piping, compressed air systems, and general-purpose fluid handling where malleable iron fittings are specified. The 3/4 inch threaded end connections follow standard NPT fitting conventions, making this a direct fit in new construction and retrofit work alike. Its Class 150 malleable iron construction meets the demands of both residential and light commercial service environments.

Installation Notes

Installation of this union should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), and the International Fuel Gas Code (IFGC) where gas service is involved. Shut off the gas or fluid supply and depressurize the line fully before disassembling or installing any threaded union. Apply an approved pipe thread sealant or PTFE tape to all male threads before assembly. Use a pipe wrench on the union body to tighten — do not use the union nut as the primary torquing point.
