Value Collection -12129-6 Black Steel Coupling 1-1/4 in Npt

Product Description

The VALUE COLLECTION -12129-6 is a Class 3000 forged carbon steel pipe coupling with a black finish, sized at 1-1/4 inches with NPT end connections. This fitting joins two sections of threaded pipe in high-pressure piping systems handling liquid or gas service up to 3000 psi. The forged carbon steel construction provides the structural integrity required for demanding industrial and mechanical applications. Licensed plumbers, pipefitters, and mechanical contractors install this coupling as part of a threaded pipe assembly in both above-ground and in-wall piping configurations.

This coupling is suited for use in industrial, commercial, and heavy-duty mechanical piping systems where Class 3000 fittings are specified. It is commonly installed in compressed air lines, gas distribution piping, hydraulic systems, and steam or fluid transfer lines that require rated threaded fittings. The 1-1/4 inch NPT sizing fits standard Schedule 80 and compatible pipe configurations. Each package contains 2 couplings. The black finish is standard for carbon steel threaded fittings in these applications.

Key Features

• Forged carbon steel construction rated for high-pressure service
• Class 3000 pressure rating at 3000 psi for liquid and gas service
• 1-1/4 inch NPT threaded end connections for standard pipe compatibility
• Black finish standard for carbon steel pipe fittings
• Sold as a package of 2 couplings per order

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-1/4 inch NPT threaded pipe systems requiring Class 3000 forged carbon steel couplings in liquid or gas service.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IPC or IFGC for gas and fluid piping systems. Depressurize and isolate the pipe section before threading the coupling onto the pipe. Apply appropriate thread sealant or PTFE tape to the male NPT threads before assembly. Do not over-torque threaded fittings; follow the pipe manufacturer and fitting specification guidelines for proper joint make-up.
