85W55 - ESAB 85W55 Replacement O-Ring Kit (5-Pack)

Stop Leaks and Keep Welding

There is nothing more frustrating than trying to lay down a perfect bead only to find out your shielding gas coverage is spotty because of a fifty-cent seal. The ESAB 85W55 O-Ring 5-Pack is your insurance policy against leaky torches and wasted gas. Designed to fit specific ESAB MIG guns and welding equipment, these O-rings are the exact size you need (.921" ID x .139" CS) to get your gear back in top shape. When an O-ring dries out, cracks, or gets nicked during a liner change, it compromises the entire system. Don't risk porosity in your welds or waste money on shielding gas blowing out the side of your handle—swap out that old seal with a fresh one.

This pack contains five O-rings, which is perfect for the welder who knows that if one thing breaks, it happens when the supply store is closed. Keep a bag in your toolbox or consumables locker so you are always ready for a quick fix. Installing these is straightforward: simply remove the old, worn-out ring, clean the groove, and roll the new 85W55 into place. A little bit of O-ring lubricant can help it seat perfectly and extend its life. These are genuine ESAB parts, meaning you don't have to worry about them being slightly too loose or too tight—they fit exactly as the manufacturer intended.

Regular maintenance of your MIG gun is key to smooth wire feeding and consistent arcs. While you are changing your contact tip or nozzle, take a second to inspect the O-rings on your gun's back end or conductor tube. If they look flattened or chewed up, grab an 85W55 from this pack. It’s a small investment that pays off in better weld quality and less frustration on the job. Whether you are a professional fabricator or a serious hobbyist, keeping your equipment sealed up tight is Welding 101.
