Value Collection 13391 Black Iron Union 1/2 in Threaded 300 Psi

Product Description

The VALUE COLLECTION 13391 is a 1/2 inch malleable iron union with a black finish, designed to connect and disconnect threaded pipe runs in plumbing, HVAC, and industrial piping systems. Rated at Class 150 with a liquid and gas pressure rating of 300 psi, this union provides a reliable, demountable joint wherever future service access is anticipated. The threaded end connections follow standard NPT fitting conventions. Licensed plumbers and pipefitters install this fitting in both new construction and retrofit applications where shutoff and reconnection of pipe sections is required.

This union is suited for residential and light commercial piping systems carrying liquid or gas media. Its black malleable iron construction makes it a common choice for gas distribution lines, compressed air systems, and water supply applications where ductile strength and a secure threaded joint are required. The black finish is standard for gas piping installations per common code practice.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IPC or IFGC. Shut off and depressurize the line before disassembly or installation. Apply thread sealant or PTFE tape appropriate to the media being conveyed before making up threaded connections. Do not overtighten; follow standard trade practice for malleable iron fittings to avoid cracking the fitting body.
