Western Enterprises AW-18 Brass Inert Arc Nipple, B-Size, 3/16" Hose Barb

Reliable Hose Repair with the Western Enterprises AW-18

When you are out in the shop or on a job site, a damaged shielding gas hose can bring your entire operation to a halt. The Western Enterprises AW-18 Inert Arc Nipple is the essential spare part you need to keep your MIG or TIG equipment running smoothly. Whether you are building a custom-length hose assembly or repairing a line that has been cut or worn, this high-quality brass nipple provides the professional connection you can trust. Don't settle for generic fittings that may leak or corrode; choose the industry standard for gas and water connections.

Designed specifically for welders, this nipple fits standard "B-Size" fittings (5/8"-18 threads), which are found on almost all standard regulators, flowmeters, and wire feeders. The barb is sized perfectly for 3/16-inch inside diameter hoses, a common size for lighter, more flexible gas lines and TIG torch water coolant hoses. The brass construction is rugged enough to withstand the daily abuse of a welding environment while resisting rust and oxidation from moisture in air lines or water coolant systems.

Installation is straightforward. Simply insert the barbed end into your 3/16" hose and secure it with a crimp ferrule or a hose clamp. The 200 PSI rating gives you peace of mind that your connection will hold up under standard regulator pressures without bursting or leaking. Whether you are routing argon to a TIG torch or setting up a water cooler for heavy-duty fabrication, the AW-18 is the reliable link in your supply chain. Made in the USA, this part ensures that your gas coverage remains consistent and your welds remain defect-free.

Ideal Applications:

• Repairing cut or leaking shielding gas hoses.
• Fabricating custom-length water lines for TIG coolers.
• Connecting gas lines to wire feeders and welding machines.
• Replacing worn-out fittings on existing equipment.
