M1115 - Miller M1115 Replacement MIG Liner 15ft .110 ID

Restore Smooth Feeding to Your 15ft Gun

There is nothing more frustrating than a MIG gun that sputters, burns back, or feeds wire erratically. Often, the culprit isn't your machine settings or the wire itself—it's the liner hidden inside your cable. The Miller M1115 Liner is the direct solution for 15-foot MIG guns that use a ring-style retainer. If you are experiencing "birdnesting" at the feeder or a pulsing arc, your old liner might be clogged with shop dirt or kinked from heavy use. Swapping it out is one of the cheapest and most effective ways to get your welder running like new again.

This liner is built tough with a steel coil design, measuring .187" on the outside and .110" on the inside. That inner diameter is spacious enough to allow compatible wires to slide through with minimal drag, yet tight enough to support the wire column and prevent buckling. It comes ready to install with the necessary ring attachment, so you don't have to fiddle with salvaging parts from your old liner.

Installation is straightforward: simply remove the old liner, slide the M1115 in, and trim the front end to the correct stick-out length for your specific diffuser and contact tip setup. Whether you are fabricating in a garage or running production welds on the line, a fresh liner ensures that the wire hits the joint exactly when you pull the trigger. Don't let a bad liner ruin your welds; keep a spare M1115 on hand to minimize downtime.
