Miller Spoolgun Nozzle Insulator Copper PTFE

This genuine Miller nozzle insulator is manufactured from copper with a PTFE body for MIG welding applications. It fits Spoolmate and Spoolmatic series spoolguns including the 15 and 30 amp models as well as XR, XR-Edge, XR-M and XR-Pistol variants. The black insulator seats FasTip nozzles and replaces part number 130831.

For MIG welders using Miller spoolguns

Welders running Miller Spoolmate or Spoolmatic spoolguns with FasTip consumables will find this insulator a direct fit. It is not intended for TIG or stick welding torches, nor for spoolguns from other brands that use a different insulator profile. Shops needing a high-temperature ceramic insulator should verify the material specification before ordering.

Check spoolgun model and nozzle series

Confirm your spoolgun appears in the compatible model list such as Spoolmatic 15, Spoolmatic 30, XR, XR-Edge or XR-Pistol series. Ensure the installed nozzle is a FasTip type so the insulator seats correctly. Verify the existing insulator part number matches 130831 or the cross-referenced numbers before purchasing.

Questions about this item

Which Miller Spoolgun models accept the 130831 nozzle insulator?

The 130831 nozzle insulator fits Spoolmate 15, Spoolmatic 15, Spoolmatic 30, XR, XR-Edge, XR-M, XR-Pistol, XR-Pistol-Pro and XR-Pistol-Pro Plus spoolguns.

Can the copper PTFE insulator be used with a standard MIG nozzle instead of a FasTip nozzle?

No, the insulator is designed specifically for FasTip nozzle series used on the listed Spoolmate and Spoolmatic spoolguns.

How can I confirm the insulator is seated correctly after installation?

The black PTFE insulator should sit flush inside the FasTip nozzle with no visible gap, and the copper body should align cleanly with the nozzle bore when the spoolgun is assembled.
