OVERVIEW

Stop Leaks and Protect Your Welds

Is your TIG torch sputtering or consuming more gas than usual? The culprit might be a dried-out or cracked O-ring. The ESAB 99W30 O-Ring (5-Pack) provides the exact replacement seals you need to restore your torch to factory performance. Leaking O-rings are more than just a nuisance; they can allow air to be sucked into your shielding gas stream, leading to porosity, oxidation, and contaminated welds that require costly rework.

Designed specifically for ESAB and legacy Heliarc torches, these O-rings fit perfectly without forcing or stretching. The .801" x .070" size is a standard configuration for specific torch body connections in this equipment line. By replacing your O-rings regularly, you ensure a tight, reliable seal that keeps your shielding gas focused on the puddle where it belongs.

Don't let a fifty-cent part ruin a critical weld. Keep this 5-pack in your toolbox so you are always ready to swap out a worn seal during routine maintenance or mid-job troubleshooting. Whether you are fixing a water leak or a gas leak, using genuine ESAB parts guarantees the durability and fitment required for professional welding environments.
