2064104 - ESAB Neoprene O-Ring .395 ID x .040 CS

Don't Let a Leaky Seal Stop Your Weld

We've all been there: you're in the middle of a critical job, and suddenly your gas coverage gets spotty, or you notice a hiss coming from your torch. Often, the culprit is a tiny, worn-out O-ring. The ESAB 2064104 O-Ring is the exact replacement you need to get your ESAB equipment back up and running smoothly. Made from tough Neoprene, this little seal is the unsung hero that keeps your shielding gas flowing where it should—onto the weld puddle—and keeps the outside air out.

Why mess around with generic hardware store O-rings that might not fit quite right? This part is sized perfectly at .395" ID by .040" thick to fit your specific ESAB gear. A proper fit means you don't have to crank down on connections to get a seal, which saves your threads and torch heads from damage. Neoprene is great because it stands up to the oil, dirt, and heat of the shop better than standard rubber, meaning you won't be swapping this out again next week.

It is always a smart move to keep a few of these in your toolbox or consumables kit. They are inexpensive insurance against downtime. Whether you are fixing up an old Heliarc torch or doing maintenance on your shop's MIG guns, having the right O-ring on hand saves you a trip to the store and gets you back under the hood faster. Swap out your dried, cracked seals with fresh ESAB neoprene and notice the difference in your equipment's performance immediately.

Installation is a breeze—just pop the old one off (careful not to scratch the groove) and roll this new one on. A little spit or O-ring lube helps it seat perfectly. Keep your welds clean and your machine happy with genuine ESAB parts.
