This PTFE liner fits Miller XR-Aluma-Pro and compatible Series spoolguns including models 300001, 300003, 300004, 301568, 301569, 301570, 301571, 301572 and 301573.

Suitable for MIG wire feed setups

Welders running .045 to .062 in aluminium or other soft wire through an XR-Aluma-Pro or listed Series spoolgun will find this liner matches the specified bore range. Shops using different spoolgun models, smaller wire below .045 in, or larger wire above .062 in should select a liner rated for those diameters.

Bore range .045 to .062 in

The liner accepts wire from .045 in minimum up to .062 in maximum, which is the single dimension that determines compatibility with your spoolgun and wire spool. Verify your wire size before ordering.
