998852 - ESAB 998852 Valve Seat for R-76/R-77 Regulators

Keep Your Regulator Running Like New

Don't let a leaking or creeping regulator slow down your welding projects. The ESAB 998852 Valve Seat is the exact replacement part you need to fix your trusted R-76 or R-77 regulator. If you've noticed your pressure gauge climbing when your torch is off, or if you're struggling to maintain a consistent flame, a worn-out valve seat is likely the culprit. Instead of spending hundreds of dollars on a brand-new regulator, you can often bring your high-quality ESAB or Purox unit back to life with this simple, affordable repair part.

We understand that your equipment is an investment. The R-76 and R-77 series are classic, heavy-duty regulators built to last a lifetime—but only if maintained properly. The valve seat is a wear item, much like brake pads on a car. Replacing it is a standard part of regulator maintenance that ensures your safety and the quality of your cuts and welds. This genuine ESAB part guarantees a perfect fit, meaning you won't have to worry about leaks or compatibility issues that often come with aftermarket knock-offs.

Safety is the number one priority when working with compressed gases. A compromised valve seat can lead to dangerous pressure spikes that threaten your hoses and downstream equipment. By installing a fresh 998852 Seat Valve, you are ensuring that your regulator shuts off flow completely when needed and delivers smooth, steady pressure when you strike an arc or light a torch. It is a small part that plays a huge role in the performance of your oxy-fuel outfit.
