85W49 - ESAB 85W49 Replacement O-Ring - .301 ID x .070 CS (Pack of 10)

Keep Your Equipment Leak-Free with ESAB 85W49 O-Rings

There is nothing more frustrating than a gas leak interrupting your workflow. Whether it's a hissing regulator, a sputtering torch, or a coolant drip, a failed O-ring is often the culprit. The ESAB 85W49 O-Ring pack is your solution for getting your gear back in top shape. Designed specifically for ESAB equipment, these O-rings provide the perfect seal you need to maintain consistent gas flow and pressure, which is directly responsible for the quality of your welds and cuts.

Why Genuine Parts Matter
When you are in the middle of a job, you need reliability. While it might be tempting to grab a generic O-ring from a hardware store assortment, welding equipment demands higher standards. The ESAB 85W49 is manufactured to exact tolerances (.301" ID x .070" thickness) to fit your specific ESAB machine or torch components perfectly. This ensures that shielding gas stays where it belongs—protecting your weld—rather than leaking out into the shop air.

Maintenance Made Easy
O-rings are consumable items; heat, pressure, and time eventually take their toll. They dry out, crack, or get compressed, losing their ability to seal. We recommend keeping this 10-pack in your toolbox so you aren't left scrambling when a seal fails. A quick swap of an O-ring can save you hours of troubleshooting and frustration. Before installing, it is good practice to inspect the seating area for debris and, if applicable, apply a tiny amount of compatible lubricant to ensure the new O-ring seats correctly without tearing.

Applications
These O-rings are used in various locations across ESAB's product line. Always check your equipment's parts manual or exploded view diagram to confirm the part number 85W49 is required for your specific repair. With ten in a bag, you'll have plenty of spares for future maintenance or for multiple machines in your shop.
