PTFE MIG welding liner

This PTFE liner feeds 0.03 to 0.035 in wire through Miller Spoolmatic 15, Spoolmatic 30, XR and XR-M guns. It replaces worn liners to restore smooth wire delivery in MIG (GMAW) welding. The pack contains three replacement liners for continuous production use.

For Miller Spoolgun operators

Welders running the listed Spoolmatic and XR series guns with 0.035 in or smaller wire will find the correct fit. Shops using larger wire diameters, non-Miller guns, or flux-cored processes without a compatible liner should select a different part.

0.035 in maximum wire diameter

The liner accepts wire up to 0.035 in and down to 0.03 in. Exceeding this maximum will cause feeding problems and premature liner wear, so wire size is the decisive specification for compatibility.

Questions about this item

How does the 0.035 in maximum wire diameter work once the liner is inside a Spoolmatic 15 gun?

The PTFE liner guides wire up to 0.035 in smoothly through Spoolmatic 15, Spoolmatic 30, XR and XR-M guns, reducing friction and preventing jams during MIG welding.

Which gun series does this liner fit and what process does that limit it to?

It fits Series Spoolmatic 15, Spoolmatic 30, XR, XR-M and Spoolgun models, so it is limited to MIG (GMAW) welding with those Miller spool guns.

What physical length or mounting style does the 136682 liner need to drop into my Spoolmatic 30A?

The liner is built to the standard length for Spoolmatic 15/30A, XR/XR-M and Series Spoolgun housings, sliding in from the rear without extra trimming.
