2064116 - ESAB Silicone O-Ring .239 ID x .070 CS - 70A Hardness

Stop Leaks and Keep Welding

There is nothing more frustrating than a hissing gas leak or a dripping coolant line interrupting your work. Often, the culprit is a tiny, worn-out O-ring that has lost its flexibility or cracked due to heat. The ESAB 2064116 O-Ring is the genuine replacement part you need to get your machine back to 100% performance. Designed specifically for ESAB equipment, this little seal plays a huge role in keeping your shielding gas where it belongs—at the weld pool—and your coolant flowing smoothly.

This isn't just any generic rubber ring you find at the hardware store. It is made from high-grade Silicone, which handles the high heat of welding much better than standard rubber. If you've ever pulled out an old O-ring that crumbled in your fingers, you know why material matters. This silicone ring stays flexible and tough, resisting the drying effects of heat and age. With a 70A hardness, it's firm enough to seal tight but soft enough to install without a struggle.

Installation is straightforward, but precision matters. This O-ring is sized exactly at .239" ID by .070" thickness. Using the wrong size, even by a fraction, can lead to pinched seals or persistent leaks. By sticking with the genuine ESAB part, you ensure a perfect fit every time. Whether you are rebuilding a torch, servicing a machine connection, or just stocking up your spare parts kit, having a few of these on hand is a smart move.

Don't let a ten-cent seal cause a hundred-dollar problem. Replace your worn O-rings during routine maintenance to prevent porosity in your welds caused by air being sucked into your gas lines. Keep your equipment running cool and efficient with this durable, heat-resistant silicone replacement.
