999155 - Victor Replacement Seal for R-76 Series Regulators

Stop Leaks and Save Your Regulator

There is nothing more frustrating in a busy welding shop than hearing the tell-tale hiss of a leaking regulator. Not only is it annoying, but it’s also literally money floating away into the air—or worse, a serious safety hazard waiting to happen. If you are running the classic Victor R-76 series regulators, you know they are built like tanks, but even tanks need maintenance. The Victor Replacement Seal for R-76 Regulators is exactly what you need to fix that leak and get back to work without shelling out cash for a brand-new unit.

Regulators work hard. They take high-pressure gas from your cylinder and step it down to a usable flow, day in and day out. Over time, the internal rubber seals can dry out, crack, or get compressed, leading to leaks or unstable pressure readings. Instead of tossing a perfectly good metal regulator body in the scrap bin, you can often bring it back to life with a simple seal replacement. This part is the genuine article from Victor (ESAB), meaning it fits right the first time and holds up to the rigors of daily shop use.

Why buy genuine? Because gas equipment isn't the place to gamble with "close enough" hardware store O-rings. This seal is designed to handle the specific pressures and gas types used in welding, cutting, and heating. Whether you are running oxygen, acetylene, or an argon mix, you need a seal that won't degrade or fail under pressure. Installing this replacement seal is a straightforward repair for those experienced with equipment maintenance, allowing you to extend the life of your trusty R-76 and keep your focus on laying perfect beads.

Don't let a fifty-cent failure cause a hundred-dollar problem. Keep a few of these seals in your maintenance kit. When you notice a pressure drop or hear a leak, you'll be ready to fix it on the spot. It’s all about keeping your gear running as hard as you do.
