Value Collection 13138 Malleable Iron Pipe Union 1/8 in 5 Pack

Product Description

The VALUE COLLECTION 13138 is a Class 150 malleable iron pipe union sized at 1/8 inch, designed for use in piping systems that carry liquid, gas, or steam. Finished with a galvanized coating for corrosion resistance, this union allows a piping run to be disconnected and reconnected without disturbing the rest of the system. It is rated at 300 psi for liquid and gas service and 150 psi for steam service. Plumbers, pipefitters, and HVAC technicians install fittings like this when maintaining or servicing threaded pipe assemblies in both residential and light commercial applications. This listing includes a package quantity of 5 units.

This union fitting is suited for threaded pipe installations carrying natural gas, air, water, or steam at the rated pressures. The 1/8 inch size fits small-diameter pipe runs commonly found in instrument lines, pilot gas lines, and other low-flow branch connections. The galvanized finish provides additional protection in environments where moisture exposure is a concern. This package of 5 is well suited for jobs requiring multiple unions or for stocking in a service van or shop inventory.

Installation Notes

Installation of threaded pipe unions should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where relevant. Always shut off the gas or fluid supply and depressurize the line before disassembling or installing union fittings. Apply an approved thread sealant or PTFE tape to male threads before assembly. Do not overtighten, as malleable iron threads can crack under excessive force.
