950391 - ESAB Brass Hex Nipple - 1/8 NPT Male x 1/4 Hose Barb

Durable Hose Repair and Adaptation Solution

When you are in the middle of a fabrication job, the last thing you need is a damaged gas line or an incompatible connection slowing you down. The ESAB 950391 Hex Nipple is the perfect solution for welders who need to repair a hose or adapt a regulator output quickly and reliably. This fitting features a 1/8-inch NPT Male thread on one side and a 1/4-inch hose barb on the other, making it an incredibly versatile part for your spare parts kit.

Built to last, this solid brass fitting stands up to the rough and tumble of the welding shop. Unlike plastic fittings that can crack or steel fittings that might rust, brass offers the perfect balance of durability and longevity. The 1/4-inch barb is designed to slide into standard 1/4-inch ID gas hoses. Once inserted, the ridges on the barb bite into the hose liner, preventing it from slipping off under pressure. Simply add a hose clamp, and you have a secure, permanent repair or new connection point ready for action.

This hex nipple is commonly used when replacing damaged fittings on wire feeders, regulators, or solenoid valves. If you have stripped a thread or snapped an old fitting, this ESAB replacement part gets your machine back up and running with minimal downtime. The hex-shaped center allows you to get a wrench on it easily, ensuring you can tighten it down securely even in tight spaces on the back of a welding machine. It is compatible with inert gases like Argon, CO2, and Helium, making it suitable for MIG and TIG applications.

Don't let a small leak compromise your weld quality. Porosity caused by air being sucked into a loose connection can ruin hours of work. By using high-quality fittings like the ESAB 950391, you ensure that your shielding gas coverage remains consistent. Keep a few of these in your toolbox for those unexpected repairs or custom rig modifications. It’s a small investment that pays off by keeping your equipment operational and your welds clean.
