14201124 - Tweco 42-116-15 MIG Gun Liner 1/16 Inch 15ft

Smooth Wire Feeding for Professional Welds

Nothing ruins a weld bead faster than a stuttering wire feed. If you are experiencing erratic arc starts, burn-backs, or bird-nesting at the drive rolls, your gun liner is often the culprit. The Tweco 42-116-15 MIG Gun Liner is the professional's choice for restoring the performance of your 15-foot MIG gun. Designed specifically for running 1/16" (1.6mm) wire, this liner provides the smooth, consistent path your wire needs to travel from the feeder to the puddle.

Built for Durability
Welding environments are tough, and your equipment needs to be tougher. This Tweco liner is made from zinc-plated spring steel. The plating isn't just for looks—it acts as a lubricant, allowing the wire to glide effortlessly through the cable even when the gun is bent or twisted around a workpiece. The spring steel construction resists kinking and crushing, ensuring that your gas flow and wire path remain unobstructed during heavy use.

Easy Maintenance
Replacing a liner is one of the most cost-effective ways to maintain your welder. This 15-foot conduit is ready to install in most standard Tweco guns, including the popular Spray Master and Classic series. It comes with the brass stop attached, so you simply slide it in, lock it down, and trim the front to match your diffuser. Don't let a clogged or kinked liner slow down your production—keep a spare Tweco 42-116-15 on hand and keep your arc smooth.
