19A11 - ESAB 19A11 Replacement Diaphragm for R-52 Regulator

Restore Precision with the ESAB 19A11 Diaphragm

The ESAB 19A11 Diaphragm is a critical replacement component designed specifically for the legendary R-52 series regulators, originally manufactured under the Purox brand and now supported by ESAB. The diaphragm is often considered the "heart" of a gas regulator; it is the dynamic element that senses downstream pressure changes and modulates the valve mechanism to maintain a constant delivery pressure. Over time, rubber components can lose elasticity, crack, or become stiff due to age and exposure to gases, leading to performance issues.

When a regulator diaphragm begins to fail, you may notice symptoms such as "creep" (where delivery pressure rises when the torch valves are closed), external leaks through the bonnet vent, or erratic flow rates during operation. Replacing a worn diaphragm with a genuine ESAB 19A11 ensures that your R-52 regulator continues to operate within its original factory specifications. This part is manufactured to exact tolerances, ensuring a perfect seal and the correct sensitivity required for precise oxy-fuel cutting and welding applications.

At Josef Gas, we understand the importance of maintaining your industrial equipment with high-quality parts. Using OEM parts like the 19A11 not only extends the lifespan of your valuable R-52 regulator but also ensures the safety of your workshop environment. A properly functioning diaphragm is essential for preventing dangerous over-pressurization events. Whether you are refurbishing a vintage Purox unit or maintaining a newer ESAB model, this diaphragm is the correct fit for the job.

Invest in the longevity of your gas equipment. The R-52 is known for its durability and reliability, and with the correct maintenance parts, it can serve your welding and cutting needs for decades. Trust genuine ESAB parts to keep your operations running smoothly and safely.
