21831 - Purox R-22 Regulator Valve Seat and Stem Repair Kit

Restore Your R-22 Regulator with the ESAB 21831 Assembly

Don't let a leaking regulator slow down your fabrication projects. The ESAB 21831 Valve Stem & Seat Assembly is the genuine repair solution for the legendary Purox/ESAB R-22 regulator series. If you have noticed that your regulator's delivery pressure gauge slowly climbs even when your torch valves are closed, you are experiencing "creep." This is a classic sign that the internal valve seat has worn out or been damaged by debris. Instead of scrapping a high-quality, heavy-duty regulator, you can bring it back to life with this simple replacement part.

The R-22 regulator is known for its durability and is a favorite among welders for its high flow capacity and rugged construction. However, like all mechanical devices, the internal soft parts eventually wear out. The 21831 assembly includes the valve stem and the sealing seat already put together, making the installation process straightforward for those experienced in equipment maintenance. By replacing the entire assembly, you ensure a fresh sealing surface that will hold pressure accurately and safely.

Using genuine ESAB parts is crucial for the longevity of your equipment. This authentic replacement part ensures that you maintain the smooth flow control and precise pressure adjustments that the R-22 is famous for. Whether you are running an oxy-fuel cutting rig or a heavy-duty heating setup, a healthy regulator is the heart of your gas supply system. A compromised seat not only wastes gas but can also create safety hazards and inconsistent flame characteristics.

This kit is an essential item for any shop's spare parts inventory. Regulator failures often happen at the most inconvenient times, and having the correct seat assembly on hand can save you days of downtime. Invest in the maintenance of your tools and ensure your welding environment remains safe and efficient. The ESAB 21831 is the cost-effective way to extend the life of your trusted R-22 regulator for years to come.
