326P204055 - ESAB Red PTFE Liner for Aluminum Wire 0.040-0.045

Smooth Feeding for Aluminum Projects

If you have ever tried to push a wet noodle through a straw, you know what it feels like to weld aluminum with the wrong liner. Aluminum wire is soft, pliable, and incredibly frustrating if your equipment isn't set up correctly. The ESAB Red PTFE Liner (326P204055) is the upgrade you need to transform your aluminum and stainless steel welding experience. Designed specifically for 0.040" to 0.045" (1.0mm - 1.2mm) wires, this liner replaces the friction-heavy steel coil in your MIG gun with smooth, slippery Teflon.

Why Choose PTFE?
Standard steel liners act like a file against soft aluminum wire, shaving off tiny metal flakes that clog your gun and cause the wire to jam or "bird-nest" at the feeder. This ESAB PTFE liner eliminates that friction. The wire glides effortlessly from the spool to the contact tip, ensuring a stable arc and consistent bead profile. The Red color coding makes it easy to identify in your toolbox, so you never accidentally install the wrong size.

Installation and Performance
Installing this liner is straightforward and is the single most effective change you can make to improve aluminum MIG performance. Whether you are fabricating boat parts, repairing aluminum trailers, or working on custom stainless exhaust systems, this liner ensures your wire feed speed remains constant. Stop fighting your machine and start welding. This liner is an essential consumable for any welder tackling non-ferrous metals with an ESAB torch.
