Value Collection B-UNI10 Black Iron Union 1 Inch 300 Psi

Product Description

The VALUE COLLECTION B-UNI10 is a black malleable iron threaded union designed for joining and disconnecting pipe runs in plumbing, gas, and mechanical piping systems. Rated at Class 150 with a liquid and gas pressure rating of 300 psi, this 1-inch union provides a reliable, removable connection point without cutting pipe. The black finish is standard for gas distribution and non-potable fluid systems. Malleable iron construction offers strength and impact resistance suitable for commercial and residential mechanical rooms, utility lines, and industrial piping. This fitting is installed by licensed plumbers, pipefitters, and HVAC technicians working on threaded pipe assemblies.

This union is suited for 1-inch threaded pipe applications in residential and commercial gas supply lines, steam systems, hydronic heating piping, and general-purpose liquid distribution. The black finish identifies it as appropriate for gas and non-potable water service in most jurisdictions. It is commonly installed in mechanical rooms, boiler rooms, and utility chases where future serviceability of the piping system is required. Install location and service type should be confirmed against local code requirements before installation.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, the International Plumbing Code (IPC), or the International Fuel Gas Code (IFGC) for gas service applications. Shut off and depressurize the piping system completely before disassembly or installation. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
