Miller 136748 Collet Nut Pair

This pack contains two Miller Electric collet nuts with a Drur slot design. They are manufactured for use with Spoolmatic 15/30A and XR series MIG welding guns. The parts are supplied new and ready for workshop fitting.

Simple hand installation

The nuts thread onto the compatible gun by hand or with a standard wrench. A common issue is cross-threading if the threads are not aligned before tightening. Debris in the thread area can also prevent the nut from seating fully and cause wire feed problems.

Verify gun model before ordering

Confirm that your equipment is a Spoolmatic 15/30A, XR-EDGE or XR/XR-M series gun. These nuts are not suited to other wire feeder models or different welding processes. The pack quantity is two, so order additional packs if more spares are required.
