38V89 - ESAB 38V89 Conduit Liner for ST-21M MIG Guns, 5/64 Inch

Keep Your Wire Running Smooth

There is nothing more frustrating than a sputtering arc caused by a bad liner. If you are running 5/64" wire through your ESAB ST-21M or ST-23 gun and feeling drag, it is time to swap out the conduit. The ESAB 38V89 is the genuine replacement liner you need to get back to smooth, buttery welding. Don't fight the feeder—replace the path.

Built for the Grind

When you are pushing heavy wire, your liner takes a beating. Metal shavings, dirt, and constant flexing wear down the inside of the coil, creating friction points that mess up your parameters. This ESAB conduit is built tough to handle the rigors of industrial environments. It is designed to guide that thick 5/64" wire straight to the tip without binding, ensuring your voltage stays steady and your beads look right.

Easy Maintenance, Better Welds

Swapping out a liner is one of the cheapest and fastest ways to fix a 'bad welder.' If your gun is acting up, check the conduit first. This assembly is ready to install into your compatible ESAB torch. Whether you are running a mechanized setup with the ST-21M or hand welding with an ST-23, keeping a fresh 38V89 in your maintenance kit means you are never down for long. Stop dealing with bird-nests and burn-backs; install a fresh liner and get back to laying metal.
