Value Collection 13388G Black Iron Union 1/8 Inch Class 150

Product Description

The VALUE COLLECTION 13388G is a black malleable iron union fitting 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 1/8 inch union allows technicians to disconnect and reconnect sections of threaded pipe without disturbing adjacent fittings. The black finish is standard for gas and low-pressure applications. Malleable iron construction provides the ductility needed to resist cracking under vibration or minor stress in mechanical systems. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this fitting type.

This union is suited for residential and light commercial piping runs where 1/8 inch threaded connections are required. Typical applications include gas supply branch lines, compressed air distribution, and steam or water service piping operating within the Class 150 pressure range. The 1/8 inch size is commonly found in pilot gas lines, instrument connections, and small-diameter service branches. Its threaded end connections conform to standard NPT fitting practice, making it compatible with standard pipe thread fittings already in service.

Designed as an OEM-style replacement or new-installation union for 1/8 inch NPT threaded piping systems operating within Class 150 service limits for liquid and gas applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IPC, or IFGC requirements. Shut off and depressurize the supply line completely before removing or installing any union fitting. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not overtighten threaded fittings; follow applicable code torque guidance and verify joint integrity under pressure before returning the system to service.
