Value Collection -12129-1 Black Coupling 1/4 in Npt Class 3000

Product Description

The VALUE COLLECTION -12129-1 is a 1/4-inch black coupling designed for high-pressure piping systems in industrial, commercial, and mechanical applications. Machined from forged carbon steel with a black finish, this fitting is rated to Class 3000, making it suitable for demanding pressure applications up to 3000 psi. It features NPT end connections on both sides for threaded assembly into standard pipe runs. Plumbers, pipefitters, and mechanical contractors install this type of fitting when joining two sections of pipe or extending a threaded run in a compact, reliable connection.

This coupling is appropriate for use in gas and liquid piping systems where a Class 3000 forged fitting is specified. The 1/4-inch size is commonly found in instrument lines, pilot gas lines, and small-diameter branch connections. NPT threads conform to standard tapered thread specifications, allowing compatibility with corresponding male-threaded pipe or fittings. The black finish is standard for carbon steel pipe fittings used in non-corrosive indoor environments and is commonly specified in gas distribution and mechanical piping assemblies.

• Sold in a package quantity of 5 units per order

Compatibility

Designed as an OEM-style replacement or standard-stock forged carbon steel coupling for use in 1/4-inch NPT threaded piping systems rated to Class 3000 service conditions.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and gas piping codes, including IFGC and ASME B31 standards where applicable. Depressurize and isolate the piping system completely before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium to NPT threads before assembly. Do not overtighten — use a pipe wrench and follow standard NPT engagement practices to avoid thread damage or fitting failure.
