2117610 - ESAB Purox R-52 Regulator Rebuild Kit

Don't Let a Leaking Regulator Stop Your Work

Your regulator is the lifeline of your oxy-fuel or shielding gas setup. If you are noticing fluctuating pressures, hearing a hiss from your tank, or seeing your gauge needle creep up when the torch is off, it is time for a rebuild. The ESAB Repair Kit R-52 is the factory-approved solution for fixing your trusty Purox or ESAB R-52 regulator. These regulators are built to last a lifetime, but the rubber and plastic parts inside eventually wear out. Instead of throwing away a high-quality piece of brass equipment, you can rebuild it yourself or have it serviced to work like new.

This kit takes the guesswork out of repairs. It comes with all the internal seals and the main seat assembly that usually causes leaks. When a regulator seat gets damaged by debris or age, it can't seal off the high-pressure gas from the cylinder, leading to dangerous pressure build-up in your hoses. Installing this kit fixes that problem instantly. It is designed to fit perfectly, so you won't be fighting with parts that are slightly the wrong size.

Keep a spare kit in your shop or tool crib to minimize downtime. Whether you are running an acetylene rig for cutting or an inert gas setup for welding, maintaining your regulator ensures consistent flame or arc characteristics. A stable arc starts with stable gas flow, and this rebuild kit is the key to maintaining that stability in your R-52 series equipment.
