Dakota Sourcing 12009 Black Iron Reducing Coupling 3/4x1/2

Product Description

The DAKOTA SOURCING 12009 is a black iron reducing coupling designed to connect two pipes of different diameters in threaded piping systems. This fitting reduces from a 3/4-inch female thread to a 1/2-inch female thread, allowing a smooth transition between pipe sizes without additional adapters. Black iron construction makes it well suited for gas distribution lines, including natural gas and propane systems, as well as general industrial piping applications. Licensed plumbers and pipefitters install this type of fitting as a standard component in residential and commercial rough-in work.

This reducing coupling is used in threaded black iron piping systems where a diameter change is required between supply and branch lines. Typical applications include gas supply runs, compressed air lines, and industrial fluid distribution where black iron fittings are specified. It is not rated for potable water service. The 3/4-inch to 1/2-inch reduction is a common size transition found in residential gas meter outlets and appliance supply drops.

Key Features

• Reduces from 3/4-inch to 1/2-inch female threaded connections
• Black iron construction suitable for gas and industrial piping
• Standard NPT thread form for compatibility with common threaded pipe and fittings
• Compact coupling body simplifies tight-space installations

Compatibility

Designed as an OEM-style replacement or standard addition for threaded black iron piping systems using NPT-threaded pipe and fittings in 3/4-inch and 1/2-inch nominal pipe sizes.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes, including the International Fuel Gas Code (IFGC) for gas piping applications. Always shut off the gas or fluid supply and verify zero pressure in the line before disassembling or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service medium before making up the joint. Pressure-test the completed assembly per local code requirements before returning the system to service.
