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

Precision Flow for Professional Cuts

When you are under the hood or handling a cutting torch, flame stability is everything. The ESAB R-52 Oxygen Regulator is designed for the professional welder who demands consistency. Whether you are performing heavy-duty oxy-fuel cutting, heating thick plate, or welding critical joints, the R-52 delivers a smooth, non-fluctuating flow of oxygen. This stability ensures that your preheat flame remains neutral and your cutting jet retains its power throughout the job, even as the cylinder pressure drops.

The R-52 is a workhorse in the shop. It features a large diaphragm that provides superior sensitivity, allowing you to dial in the exact pressure required for your specific torch tip size. The adjustment knob is designed for easy operation, even when wearing heavy welding gloves. The CGA 540 inlet connects securely to your oxygen tank, while the standard 9/16"-18 outlet fits all standard Grade R and Grade T hoses. The regulator's ability to handle inlet pressures up to 3000 PSIG means it is ready for modern high-pressure cylinders.

Durability is a key feature of the R-52. We know that shop environments are tough—regulators get knocked, dragged, and exposed to sparks. The forged brass body of the R-52 can take a beating and keep performing. The gauges are clear and distinct, helping you monitor your usage so you don't run out of gas in the middle of a cut. Upgrade your oxy-fuel setup with a regulator that works as hard as you do.
