2221978 - ESAB Silicone O-Ring 1.8125 ID x .103 CS 60A Replacement Seal

Keep Your Equipment Running Leak-Free

In the world of professional welding, even the smallest component plays a massive role in the reliability of your gear. The ESAB 2221978 O-Ring is a genuine replacement part designed to keep your ESAB equipment operating at peak performance. Over time, seals and O-rings can dry out, crack, or become compressed, leading to frustrating leaks that can disrupt gas flow, coolant circulation, or internal pressure. Replacing these worn-out seals is a simple yet vital maintenance task that prevents minor issues from turning into major equipment failures.

This particular O-ring is made from durable Silicone, a material known for its ability to handle heat. Since welding environments are naturally hot and harsh, standard rubber seals often degrade quickly. This silicone replacement resists that heat, ensuring it stays flexible and keeps a tight seal longer. With a 60A hardness rating, it is pliable enough to install easily without damaging the seal, but tough enough to hold up under the pressures of daily shop use. It measures 1.8125 inches on the inside diameter with a thickness of roughly 0.103 inches, ensuring a perfect fit for the specific groove it was designed for.

Don't risk your weld quality or machine safety with ill-fitting generic parts. Using the correct ESAB O-ring guarantees that the dimensions are exact, eliminating the guesswork of sizing. Whether you are troubleshooting a gas leak in a wire feeder connection or rebuilding a torch assembly, having the right spare parts on hand is key to minimizing downtime. This O-ring is a direct replacement, meaning you can swap it out and get back to welding with confidence, knowing your equipment is sealed up tight and ready for the job.
