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

Genuine Replacement Diaphragm for R-52 Regulators

The ESAB 19A11 is the authentic replacement diaphragm for the Purox / ESAB R-52 single-stage regulator. In the world of oxy-fuel equipment, the R-52 is a workhorse known for its robust design and reliability in heavy-duty industrial environments. However, even the most durable regulators require maintenance. The diaphragm is the primary moving part within the regulator assembly, flexing thousands of times during use to balance the spring force against the gas pressure. This constant motion, combined with the chemical properties of welding gases, eventually necessitates replacement.

This diaphragm is engineered from high-grade elastomeric materials chosen for their flexibility, strength, and resistance to specific gas types. It is designed to respond instantly to changes in demand, opening the valve when you strike an arc or trigger a cutting torch, and closing it securely when flow stops. A compromised diaphragm can lead to unstable flames, difficulty in setting neutral flames, and potential safety hazards. If your R-52 regulator is exhibiting signs of pressure drift or leakage, the 19A11 is likely the part you need to restore functionality.

Why Choose Genuine ESAB Parts?
Regulators control high-pressure gases, often reducing cylinder pressures of over 2000 PSI down to workable pressures. The structural integrity and precise dimensions of internal components are vital for safety. Generic or ill-fitting diaphragms can fail under pressure or cause the regulator to malfunction. The ESAB 19A11 is manufactured to the original Purox blueprints, guaranteeing a perfect fit between the regulator body and the bonnet.

Professional repair technicians and safety-conscious welders rely on OEM parts to maintain the certification and safety standards of their equipment. By installing the 19A11, you are ensuring that your R-52 regulator retains the performance characteristics that made it an industry standard. Keep your cuts clean and your welds strong with consistent gas flow provided by a well-maintained regulator.
