0459990038 - ESAB PSF Series Neck Insulator Washer Black

Keep Your Torch Running Smoothly

Welding torches take a beating, and the internal components are often the first to show signs of wear. The ESAB Neck Insulator Black (0459990038) is the small but mighty part that keeps your MIG gun safe and operational. If your current insulator is cracked, burnt, or missing, you risk arcing out your nozzle against the contact tip or the neck itself. This direct replacement part restores the safety barrier in your torch, ensuring the electricity goes into the wire and not into the nozzle.

Easy Replacement for PSF Guns

Designed for the welder who needs reliable equipment, this insulator fits the classic ESAB PSF line, including the PSF 250, 305, 405, and 505 guns. Swapping it out is a simple maintenance task that can prevent costly downtime. Simply remove the nozzle, slide off the old washer, and pop this new black insulator in place. It creates a secure seal and a safe electrical break, allowing you to focus on laying down perfect beads without worrying about equipment malfunctions.

Genuine ESAB Quality

Don't settle for generic knock-offs that might melt or fit poorly. This is a genuine ESAB part, built to the exact specs of your PSF torch. It handles the heat of daily welding and resists spatter buildup better than inferior plastics, giving you a longer service life and better value for your money.
