227161 - Miller 227161 Teflon Liner for XR Aluma-Pro 4-Inch Head Tubes

Smooth Aluminum Feeding with Miller 227161 Teflon Liners

Welding aluminum can be a headache if your equipment isn't set up correctly. The soft wire loves to kink, bird-nest, and shave against standard steel liners. That's where the Miller 227161 FasTip Teflon Liner comes in. This 4-inch jump liner is designed specifically for the head tube of your Miller XR Aluma-Pro gun. Because it is made of Teflon, it provides a slick, frictionless surface that allows soft aluminum wire (.030 to .040 inch) to glide through smoothly without snagging or deforming.

This liner is part of the FasTip system, which is all about speed and convenience. When you are in the middle of a job, you don't want to spend twenty minutes fighting with your torch maintenance. The FasTip design allows you to swap out consumables quickly so you can get back under the hood. This specific liner fits the 4-inch air-cooled head tubes, acting as the final bridge for the wire before it hits the contact tip. It is a small part, but it plays a huge role in preventing those frustrating burn-backs and feed stoppages that ruin your rhythm.

If you are running a push-pull gun setup for aluminum, you know that the "push" and the "pull" need to work in perfect harmony. Friction is the enemy. By replacing your head tube liner regularly with this genuine Miller Teflon part, you reduce drag significantly. This means your drive rolls don't have to work as hard, and your wire comes out straight and steady. Whether you are building boat hulls, fixing trailers, or doing custom fabrication, this liner helps you lay down those stack-of-dimes beads with confidence.

Don't let a cheap or worn-out liner compromise your aluminum welds. The Miller 227161 is the exact fit for your 4-inch assembly, ensuring that your gas coverage remains consistent and your wire stays on track. Grab a few spares for your toolbox so you are never caught off guard by a clogged liner in the middle of a critical project.
