Value Collection -12129-3 Black Coupling 1/2 in Npt Class 3000

Product Description

The VALUE COLLECTION -12129-3 is a 1/2-inch black pipe coupling rated for Class 3000 service. Forged from carbon steel with a black finish, this fitting is designed for joining two sections of threaded pipe in high-pressure piping systems. The NPT (National Pipe Taper) thread form creates a pressure-tight seal when assembled with compatible fittings and pipe. At a 3000 psi pressure rating, this coupling is suited for demanding liquid and gas applications where standard fittings would be undersized. Plumbers, pipefitters, and industrial maintenance technicians typically source and install this type of fitting.

This coupling is used in residential, commercial, and industrial piping systems where black iron or carbon steel pipe is specified. Common applications include natural gas distribution, compressed air lines, steam service, and hydraulic piping. The Class 3000 rating makes it appropriate for high-pressure runs where the fitting must match the strength of Schedule 80 pipe. Sold in a package of 5 units, making it practical for multi-joint jobs or shop inventory. NPT threads conform to ASME B1.20.1 standards for interchangeability with standard threaded pipe and fittings.

Key Features

• Forged carbon steel construction for strength in high-pressure applications
• Class 3000 rated to 3000 psi for liquid and gas service
• 1/2-inch NPT end connections for standard threaded pipe compatibility
• Black finish suitable for gas, steam, and air piping systems
• Sold as a 5-pack for multi-joint projects or bench stock

Compatibility

Designed as an OEM-style threaded coupling for use with 1/2-inch NPT black iron or carbon steel pipe in Class 3000 piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off and depressurize the line completely before disassembly or fitting installation. Apply appropriate thread sealant or PTFE tape to NPT threads before assembly. Do not over-torque threaded connections; hand-tighten first, then use a pipe wrench to achieve a proper seal without damaging threads.
