17422237 - Tweco Supra MIG Gun Conduit Liner SW415CC

Get Your Feed Back on Track

Is your wire sputtering, dragging, or jamming right when you're in the middle of a bead? It might be time to replace your liner. The Tweco 1742-2237 Conduit (SW415CC) is the direct replacement liner you need for your Tweco Supra MIG gun. We all know that the liner is the unsung hero of the MIG gun; if it's dirty, kinked, or worn out, even the best welder can't lay a smooth bead. This conduit is designed to fix those frustrating feed issues and get you back to welding with a stable, consistent arc.

Built tough by Tweco, this liner is made to withstand the twisting and pulling that happens on the job site. It provides a smooth, low-friction path for your welding wire, which is essential for preventing those annoying birdnests at the drive rolls. If you've noticed that your wire speed feels inconsistent or you're feeling excessive drag in the gun cable, swapping out your old conduit for this fresh SW415CC unit is often the quick fix that solves the problem. It's a small investment that saves you a ton of headache and wasted wire.

Don't let a bad liner slow down your project. This replacement part fits perfectly into compatible Supra series guns, meaning you won't have to fight to get it installed. Just trim to length if necessary (following standard liner installation tips), secure it, and you're ready to burn wire again. Keep a spare 1742-2237 in your toolbox so you're never stuck waiting on parts when you should be welding. Smooth feeding equals better welds, and this Tweco conduit delivers exactly that.
