Value Collection 12129 Black Pipe Coupling 1/8 Inch Npt

Product Description

The VALUE COLLECTION 12129 is a forged carbon steel pipe coupling with a black finish, sized at 1/8 inch NPT. Designed for threaded pipe assembly in high-pressure applications, this coupling joins two sections of pipe along a straight run. The Class 3000 pressure rating supports up to 3000 psi, making it suitable for demanding liquid and gas service lines. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers. The forged carbon steel construction provides the strength and durability required in pressurized systems where cast fittings are not acceptable.

This coupling is used in residential and commercial plumbing, gas distribution, and industrial piping systems where 1/8 inch NPT threaded connections are required. The black finish is standard for gas service and non-potable liquid lines. Class 3000 forged fittings are commonly specified in high-pressure steam, hydraulic, and compressed gas applications. This fitting ships in a package quantity of five units, suitable for jobs requiring multiple connections on the same run.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. Shut off and depressurize the line fully before disassembling or threading any fittings. Use an approved pipe thread sealant or PTFE tape rated for the specific service medium. NPT threads are tapered and must not be overtightened, as this can crack the fitting or damage the mating pipe threads.
