0366397002 - ESAB PSF Series MIG Gun Insulator Bushing 10-Pack

Protect Your Torch and Weld Quality

For professional welders using ESAB PSF series MIG guns, the Insulating Bushing (0366397002) is an essential component for safe and effective welding. This bushing sits inside the front end of your torch, acting as a critical electrical barrier between the live contact tip holder and the gas nozzle (if the nozzle is meant to be electrically isolated) or simply as a thermal and electrical shield for the swan neck. Over time, heat and spatter can degrade this insulation, leading to erratic arcs, short circuits against the workpiece, or even damage to the torch neck itself. Replacing this bushing regularly is a small step that prevents big headaches.

This pack of 10 ensures you have plenty of spares in your toolbox. When you are in the middle of a long bead or working in a tight position, the last thing you need is a torch malfunction caused by a cracked or carbonized insulator. These genuine ESAB bushings are molded from high-heat resistant material that stands up to the intense temperatures of MIG welding. They fit perfectly into PSF torches, ensuring that your gas nozzle seats correctly and that shielding gas flow remains laminar and undisturbed.

Installation is quick and requires no special tools—simply disassemble the front end of the gun, remove the old, worn bushing, and slide the new one into place. By maintaining this part of your torch, you ensure consistent electrical characteristics and protect the more expensive components of your MIG gun from heat damage and electrical shorts. Keep your arc smooth and your equipment in top shape with these original ESAB replacements.
