Value Collection -12129-5 Black Coupling 1 Inch Npt Class 3000

Product Description

The VALUE COLLECTION -12129-5 is a forged carbon steel black coupling designed for high-pressure piping systems in industrial and commercial applications. Sized at 1 inch with NPT end connections, this coupling is rated to Class 3000 and carries a 3000 psi pressure rating, making it suitable for demanding liquid and gas service. The black finish is a standard mill-applied coating typical of carbon steel fittings. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this type of fitting. This listing includes a package quantity of five couplings per order.

This coupling is used in high-pressure threaded piping assemblies where forged carbon steel construction is required. Common applications include steam lines, compressed air systems, hydraulic lines, and gas distribution piping in commercial and industrial facilities. The Class 3000 rating aligns with ASME B16.11 standards for forged fittings, making this coupling appropriate for systems that demand reliable pressure containment at 1-inch connection points. It is not intended for use with stainless or corrosive-media systems where carbon steel is unsuitable.

• Sold in a convenient 5-pack quantity per package

Compatibility

Designed as an OEM-style threaded coupling for use in 1-inch NPT high-pressure carbon steel piping systems rated to Class 3000 service conditions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or ASME B31.3 for process piping. Isolate and fully depressurize the piping system before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to NPT threads per manufacturer and code guidance. Do not overtighten threaded connections, as this can damage threads or crack fittings.
