OVERVIEW

Stop Leaks and Get Back to Welding

Don't let a worn-out seal compromise your safety or weld quality. The ESAB 86W75 O-Ring is the exact replacement part you need to fix leaks in your welding gear. Over time, O-rings can dry out, crack, or become compressed, leading to gas leaks that waste expensive consumables and pose potential safety hazards. This replacement O-ring is made from durable Buna-N rubber, the standard choice for welding equipment due to its excellent resistance to wear and tear.

Measuring 0.114 inches on the inside diameter and 0.070 inches thick, this O-ring is designed to fit perfectly into the grooves of compatible regulators, torch valves, and adaptors. The 70A durometer hardness means it is tough enough to hold a seal under pressure but flexible enough to install without damaging the part. If you are rebuilding a Victor or ESAB regulator, or servicing a torch handle, this small component plays a huge role in the functionality of your tool.

Replacing your O-rings is a simple, low-cost maintenance task that can extend the life of your equipment significantly. We recommend keeping a few of these 86W75 O-rings in your toolbox so you are never stuck waiting for parts when you should be burning rod. Simply remove the old, damaged O-ring, clean the groove, and roll this new one into place for an instant, factory-quality seal.

Why Choose Genuine Parts?

  • Perfect Fit: Guaranteed dimensions for ESAB/Victor equipment.
  • Durable Material: Resists drying out and cracking better than generic rubber.
  • Safety: Ensures a proper gas-tight seal to prevent hazardous leaks.
