1/4 Inch NPT Female Brass Pipe Coupling

Reliable Connections for Your Shop Air and Gas Lines

Every welder knows that a smooth-running shop depends on reliable connections, not just in the electrical arc, but in the gas and air lines that support the equipment. The Forney 39113 Brass Coupler is a small but essential problem-solver for your workshop. Designed to connect two 1/4-inch male NPT fittings, this coupler allows you to extend hoses, join piping sections, or adapt equipment configurations with ease. Whether you are setting up a new plasma cutter air supply or re-routing shielding gas lines, having high-quality brass fittings on hand is a must.

Why Brass?
In a welding environment, equipment takes a beating. Steel fittings can rust and seize over time, especially in compressed air lines where moisture buildup is inevitable. The Forney 39113 is made from solid brass, which naturally resists corrosion and rust. This means that if you ever need to disassemble the line for maintenance, the threads are less likely to be frozen shut, saving you frustration and downtime. Additionally, brass is softer than steel, which helps it create a better seal against harder male pipe threads, reducing the chance of annoying leaks that waste gas and compressor energy.

Easy Installation
The coupler features a hex-shaped body, giving you a solid grip with your wrench. No more struggling with round fittings that slip in your pliers. Simply apply a little thread tape or pipe dope to your male ends, thread them into the Forney 39113, and tighten until snug. The precision 1/4" NPT threads ensure a secure fit that holds up to standard shop pressures.

Versatile Utility
While often used for compressed air, this coupler is also suitable for water and inert gases. It's the perfect spare part to keep in your toolbox. When a line comes up short or you need to bridge two male connectors, this simple, durable fitting gets you back to work quickly. Don't let a missing connection stop your fabrication project; rely on Forney's industrial-grade brass fittings to keep your shop flowing smoothly.
