The VALUE COLLECTION -12129-2 is a 3/8 inch NPT black coupling machined from forged carbon steel with a black finish. Rated to Class 3000, this fitting handles high-pressure liquid and gas service up to 3000 psi. It is a threaded pipe coupling used to join two sections of pipe in a straight run. Plumbers, pipefitters, and gas system installers use this fitting in industrial and commercial piping systems where strength and pressure integrity are required. The forged construction provides dense, consistent material throughout the body, making it suitable for demanding service environments.
This coupling is suited for residential and commercial installations where 3/8 inch NPT threaded connections are required. Typical applications include gas distribution piping, compressed air lines, hydraulic systems, and general fluid transfer lines. The black finish is standard for carbon steel pipe fittings used in gas service. It ships in a package quantity of five units, making it practical for jobs requiring multiple connections.
Designed as an OEM-style replacement and standard-use fitting for 3/8 inch NPT threaded pipe systems in gas, air, and fluid service applications.
Installation is performed by licensed plumbers or pipefitters in accordance with applicable code requirements such as the IFGC or IPC. Shut off all gas or fluid supply and depressurize the line completely before removing or installing any fitting. Apply appropriate thread sealant rated for the service medium — pipe dope or PTFE tape — following the manufacturer and code guidelines for the application. Inspect threads on both the fitting and mating pipe for damage before assembly.
