Oxygen regulator for general-purpose welding
The Radnor 64003034 is a single-stage oxygen regulator built for general-purpose welding tasks. It connects to a CGA 540 cylinder valve through a male 0.908"-14 NGO inlet. The brass body houses a sintered inlet filter and a stem-type seat mechanism. Heavy-duty rating and a larger regulator body support demanding workshop use.
Single-stage pressure delivery limits
A single-stage design means outlet pressure rises as the cylinder empties, so the operator must adjust the knob during long jobs. Maximum outlet pressure is 125 psig through a male 9/16"-18 UNF outlet. The regulator does not compensate automatically for falling inlet pressure. Users who need constant pressure without manual correction should consider a two-stage alternative.
Brass construction with sintered filter
The brass body resists corrosion and withstands heavy-duty handling in industrial environments. A sintered inlet filter traps debris before it reaches the seat mechanism, reducing the risk of leaks or contamination. Male inlet and outlet threads require matching fittings on the hose and cylinder. California Proposition 65 warnings apply for cancer and reproductive-harm chemicals.

Questions about this item
Should I choose this single-stage regulator or a two-stage model for my oxygen setup?
This Radnor unit is a single-stage CGA 540 regulator rated for 125 psig maximum outlet pressure; single-stage designs are typical for general-purpose welding where supply pressure remains steady.
What does the 125 psig outlet pressure mean when I am actually welding?
The regulator will deliver oxygen at up to 125 psig to your torch, which covers standard cutting and welding tasks; actual flow depends on your tip size and hose length.
How does the CGA 540 inlet with 0.908"-14 threads connect to my cylinder?
The male 0.908"-14 NGO inlet threads directly onto a standard oxygen cylinder valve; the outlet is a male 9/16"-18 UNF fitting for your hose connection.
