20A16 - ESAB R-52 Heavy Duty Oxygen Regulator CGA 540

Reliable Industrial Gas Control

For industrial gas distributors and facility managers, the reliability of downstream equipment is paramount to maintaining safety and efficiency. The ESAB R-52 Oxygen Regulator (SKU: 20A16) represents a standard of excellence in heavy-duty gas regulation. Designed to handle the rigors of daily cylinder changeouts and high-pressure flows, this regulator is built on a legacy of performance associated with the Oxweld and Purox lines. Its robust construction ensures that it can withstand the physical demands of transport, storage, and active use in fabrication yards, shipyards, and manufacturing plants.

The R-52 features a forged brass body and bonnet, providing exceptional resistance to corrosion and mechanical impact. Unlike lighter-duty regulators that may suffer from seat failure under frequent cycling, the R-52 utilizes a patented stem-type seat mechanism. This design minimizes wear and tear, significantly extending the service interval and reducing the total cost of ownership for your fleet of equipment. The regulator is equipped with a sintered bronze inlet filter, a critical component that prevents particulate matter from the cylinder or hose from entering the high-pressure seat area, thereby preventing leaks and creep.

Safety is engineered into every aspect of the ESAB R-52. It includes a self-reseating relief valve (where applicable by model iteration) to protect downstream equipment from over-pressurization. The gauges are protected and easy to read, allowing operators to verify cylinder contents and delivery pressure at a glance. For gas suppliers looking to provide their clients with equipment that matches the quality of their gas products, the ESAB R-52 is the definitive choice for oxygen service.
