14401125 - Tweco 44-564-25 MIG Gun Liner, 1/16-5/64 in, 25 ft

Restore Smooth Wire Feeding with the Tweco 44-564-25 Liner

Is your MIG gun sputtering, or does the wire feel like it's dragging? A worn-out or clogged liner is often the culprit behind poor weld quality and frustration in the shop. The Tweco 44-564-25 (Stock #1440-1125) is the professional's choice for restoring factory-fresh performance to your 25-foot MIG gun. Designed specifically for running heavier wires like 1/16" and 5/64", this liner is built to handle the heat and mechanical stress of high-amperage welding.

Why Choose a Tweco 44 Series Liner?
Tweco's 44 Series liners are the industry standard for a reason. They are wound from premium spring steel that resists kinking, even when you are working in tight corners or have the cable looped. The wire is zinc-plated, which serves a dual purpose: it prevents the liner from rusting inside your cable (which can contaminate your weld pool), and it provides a slick surface for the welding wire to glide against. This means less strain on your wire feeder motor and a smoother, more consistent arc at the tip.

Perfect for Extended Reach
At 25 feet long, this liner is intended for extended-length gun assemblies or push-pull systems where standard 15-foot liners just won't reach. Whether you are welding on a large trailer frame or reaching across a jig, this liner ensures your wire gets there without binding. Installation is straightforward—simply remove the old liner, slide this one in until the brass stop seats, and trim the front end to the correct length for your specific gun model and gas diffuser setup.

Don't let a $20 part ruin a $2000 job. Keep your wire feeding smoothly and your welds looking great with a genuine Tweco conduit liner. It is compatible with mild steel solid wires and flux-cored wires, making it a versatile addition to your maintenance kit.
