Value Collection B-UNI05 Black Malleable Iron Union 1/2 in

Product Description

The VALUE COLLECTION B-UNI05 is a 1/2 inch black malleable iron union 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 union allows technicians to disconnect and reconnect sections of threaded pipe without disturbing the rest of the run. The black finish is standard for gas piping applications. Malleable iron construction provides the ductility and strength required for mechanical and gas service environments. Licensed plumbers, pipefitters, and HVAC technicians are the primary installers of this fitting.

This union is suited for residential and light commercial gas lines, compressed air systems, hydronic heating piping, and general-purpose liquid or gas distribution where NPT threaded connections are specified. The 1/2 inch size fits common branch and main line sizes found in residential gas appliance connections and small-diameter mechanical piping. It is sold individually, making it a straightforward single-fitting replacement or addition to an existing threaded system.

Key Features

• 1/2 inch threaded end connections for standard NPT pipe
• Malleable iron construction for ductility and impact resistance in mechanical service
• Black finish suited for gas piping applications
• Class 150 rated with 300 psi liquid and gas pressure rating
• Allows pipe disconnection and reconnection without cutting or unthreading the full run

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch NPT threaded piping systems in residential and commercial mechanical applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local mechanical codes and the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) where applicable. Shut off and depressurize the gas or fluid supply completely before disassembling any threaded union. Apply an appropriate thread sealant or PTFE tape rated for the service media before making up the threads. Inspect all three union components for damage before assembly and confirm the union seats fully before returning the system to service.
