Value Collection 13584 Black Iron Union 3/4 in Threaded Class 300

Product Description

The VALUE COLLECTION 13584 is a 3/4-inch black malleable iron union designed for threaded pipe assemblies in plumbing, gas distribution, and industrial piping systems. Built to Class 300 standards, it carries a liquid and gas pressure rating of 1500 psi, making it suitable for demanding service conditions. The black finish is applied over malleable iron construction, providing corrosion resistance appropriate for general-purpose applications. This fitting is typically installed by licensed plumbers and pipefitters working on ferrous pipe systems where a break-apart union connection is required for future serviceability.

This union is used in residential and light commercial gas piping, compressed air lines, and water distribution systems where threaded malleable iron fittings are specified. The 3/4-inch size fits standard NPT threaded pipe of the same nominal diameter. Its Class 300 pressure rating makes it appropriate for applications where pressure demands exceed the limitations of standard Class 150 fittings. It is sold in a package quantity of 5 units per order.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes, including IFGC requirements for gas service applications. Shut off all gas or fluid 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. Do not overtighten, as malleable iron threads can be damaged by excessive torque.
