A-163 - Western Enterprises A-163 Brass Adaptor 1/4" FNPT x 1/4" Hose Barb

Secure Your Gas Lines with the Western Enterprises A-163 Adaptor

For welders and fabricators, maintaining a leak-free gas delivery system is critical for both safety and weld quality. The Western Enterprises A-163 Brass Adaptor is the perfect solution for customizing or repairing your gas hoses and regulator setups. This fitting allows you to convert a 1/4-inch male NPT outlet—commonly found on regulators, manifolds, or hard piping—into a connection point for a 1/4-inch ID rubber hose.

Built to last, this adaptor is machined from solid brass, a material that stands up to the rough conditions of a welding shop. Unlike cheaper fittings that may crack or corrode over time, the A-163 maintains its structural integrity, ensuring that your shielding gas or fuel gas lines remain secure. The 1/4-inch female NPT threads are cut precisely to ensure a solid mechanical connection, while the barbed end provides excellent grip on the hose interior.

Installation is straightforward. Simply apply a suitable thread sealant (like Teflon tape or pipe dope compatible with your gas) to the male pipe thread, screw on the A-163 adaptor, and tighten it down. Then, push your 1/4-inch ID hose onto the barb and secure it with a hose clamp or crimp ferrule. The fitting is rated for pressures up to 200 PSIG, giving you plenty of headroom for standard welding gas pressures, which typically operate well below that limit.

Whether you are building a custom manifold, extending a line, or replacing a damaged fitting, having the right adaptor in your toolbox can save the day. The Western Enterprises A-163 offers the professional quality and peace of mind that professional welders demand from their equipment.
