Value Collection -12129-8 Black Coupling 2 in Class 3000 Npt

Product Description

The VALUE COLLECTION -12129-8 is a 2-inch black coupling designed for high-pressure pipe systems in industrial, commercial, and mechanical applications. Forged from carbon steel with a black finish, this fitting meets Class 3000 pressure ratings, making it suitable for demanding liquid and gas service. The NPT end connections allow for straightforward threaded installation on standard pipe runs. Licensed plumbers, pipefitters, and mechanical contractors typically specify Class 3000 fittings for pressure-critical systems where a standard 150-class fitting is insufficient. This coupling ships in a package quantity of two.

This coupling is used in threaded pipe assemblies carrying liquids or gases at elevated pressure ratings up to 3000 psi. Class 3000 carbon steel fittings are common in industrial plant piping, commercial mechanical rooms, oil and gas distribution lines, and steam or hydraulic service where forged steel construction is required. The black finish is standard for carbon steel pipe fittings in non-corrosive gas and liquid service environments.

Key Features

• Forged carbon steel construction rated for Class 3000 service
• 2-inch NPT end connections for standard threaded pipe installation
• 3000 psi liquid and gas pressure rating
• Black finish standard for carbon steel pipe fittings
• Package quantity of two units per order

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch NPT threaded pipe systems requiring Class 3000 forged carbon steel couplings in liquid or gas service.

Installation Notes

Installation should be performed by a licensed pipefitter or plumber in accordance with applicable mechanical codes such as the IFGC or ASME B31.3. Depressurize and isolate the pipe system fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the NPT threads before assembly, and tighten to a secure connection without over-stressing the fitting. Inspect for leaks after pressurizing the system.
