Value Collection 12131 Black Steel Reducing Coupling 5-pack

Product Description

The VALUE COLLECTION 12131 is a black steel reducing coupling designed to connect pipe or tubing of two different diameters in threaded piping systems. The coupling features a 1/4-inch female thread on one end and a 1/8-inch female thread on the other, with NPT threading on both connections. Constructed from steel with a black finish, it provides the mechanical strength needed for industrial, commercial, and residential piping applications. Plumbers, pipefitters, and HVAC technicians use this fitting when transitioning between 1/4-inch and 1/8-inch NPT pipe runs. Each order includes five couplings.

This reducing coupling is suited for threaded pipe assemblies in gas, air, or fluid distribution lines where a diameter reduction is required. The black finish is standard for low-pressure gas piping applications in residential and light commercial systems. It is a common fitting in instrument lines, pneumatic systems, and compressed air distribution as well as natural gas and propane supply lines. Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians working within applicable codes.

Key Features

• Reduces from 1/4-inch NPT to 1/8-inch NPT in a single fitting
• Steel construction for mechanical durability in demanding service environments
• Black finish standard for gas piping and industrial applications
• NPT threaded end connections for secure, leak-resistant assembly
• Sold in a convenient 5-pack to support multi-point installations or stock replenishment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for threaded NPT piping systems requiring a 1/4-inch to 1/8-inch reduction.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing and mechanical codes such as the IPC or IFGC. Shut off the gas or fluid supply and depressurize the line completely before removing existing fittings or installing new ones. Apply an appropriate thread sealant or PTFE tape to NPT threads before assembly. Do not overtighten threaded steel fittings, as this can crack adjacent fittings or damage threads.
