97W33 - ESAB 97W33 Buna-N O-Ring Replacement Seal

Keep Your Gear Leak-Free with the ESAB 97W33 O-Ring

Every welder knows that even the smallest leak can cause the biggest headaches. Whether it's shielding gas escaping before it hits the puddle or coolant dripping onto your workpiece, a failed seal is a problem you need to fix fast. The ESAB 97W33 O-Ring is the reliable replacement part you need to get your equipment back to 100%. Made from tough Buna-N rubber, this O-ring is built to withstand the dirty, oily, and demanding environment of a welding shop without breaking down or swelling unexpectedly.

This specific O-ring measures .362 inches on the inside with a thickness of .103 inches. It’s a common size found in various parts of your welding setup, from the back end of your MIG gun to the connections on your gas regulator or water cooler. Because it is a genuine ESAB part, you don't have to worry about it being slightly off-size or made of cheap rubber that cracks after a week. It fits right the first time, creating a tight seal that holds pressure and keeps fluids where they belong.

Maintenance is a key part of welding. Over time, O-rings dry out, crack, or get flattened, leading to those annoying hissing sounds or wet spots. Keeping a pack of ESAB 97W33 O-rings in your toolbox is a smart move for any fabricator. The 70A durometer rating means the rubber is hard enough to resist getting chewed up during installation but soft enough to compress and fill the gap perfectly. It stands up well against oil, grease, and water, which are always present around industrial machinery.

Don't let a ten-cent seal ruin a thousand-dollar job. When you are troubleshooting a loss of gas coverage or a coolant leak, checking your O-rings should be step one. Swapping out a worn seal with a fresh ESAB 97W33 is a quick, inexpensive fix that restores your machine's performance instantly. Whether you are running a busy fabrication shop or maintaining your own rig in the garage, trusting genuine replacement parts ensures your torch stays cool, your gas flows smooth, and your welds stay clean.
