Oxygen regulator for cutting and welding

The Victor 0781-0043 is a single-stage oxygen regulator built for cutting, heating and welding tasks. It connects to a CGA 540 cylinder valve through a 0.908-14 male inlet and delivers gas through a 9/16-18 male UNF outlet. The brass body and neoprene diaphragm handle industrial use.

Single-stage pressure control limits

A single-stage design reduces cylinder pressure to the working outlet in one step, so outlet pressure rises as the cylinder empties. The maximum outlet gauge reads 4,000 psig while the delivery pressure is capped at 125 psig. Operators must re-adjust the T-handle during long jobs to maintain a steady flow.

CGA 540 inlet decides compatibility

This regulator only fits oxygen cylinders equipped with a CGA 540 valve. It will not connect to fuel-gas, inert-gas or medical cylinders that use different CGA numbers. Verify the cylinder valve marking before purchase.

Questions about this item

Which outlet pressure version should I choose for cutting, heating or welding with oxygen?

The regulator delivers a maximum outlet pressure of 125 psig, which is the single setting for cutting, heating and welding tasks.

What does the 4,000 psig maximum gauge outlet pressure mean when the regulator is connected to a cylinder?

It indicates the highest pressure the gauge can display from the supply side; the working outlet pressure is limited to 125 psig.

How does the CGA 540 inlet with 0.908-14 threads affect compatibility with my oxygen cylinder?

CGA 540 is the standard oxygen cylinder connection; the 0.908-14 male inlet threads directly onto a matching CGA 540 cylinder valve.
