  • Main materialHAWA
  • Product typeGas Regulators
  • Single-stage design reduces complexity for reliable CO₂ delivery

Carbon Dioxide Regulator CGA-320

This single-stage brass regulator controls carbon dioxide flow from high-pressure cylinders. It is built for general-purpose welding and industrial gas applications where a stable outlet pressure is required. The unit connects directly to CGA-320 cylinder valves for immediate use.

Brass Body with Stainless Diaphragm

The brass body measures 3.64 in diameter and carries a 4,000 psi supply-pressure gauge plus a delivery gauge sized at 2 1/2 in. A 5/8 in.-18 RH outlet fitting accepts standard hose connections while the stainless-steel diaphragm resists corrosion during extended service. ETL listing to UL252 confirms compliance with recognised safety standards.

Delivery Range 5 to 150 psi

The adjustable outlet span of 5 to 150 psi determines whether this regulator matches the pressure needs of a specific welding process or gas-shielding setup. Buyers who require pressures outside this window or a different inlet connection will need another model.

Questions about this item

What does the CGA-320 inlet connection limit the regulator to?

The CGA-320 inlet connects only to carbon dioxide cylinders, so the regulator cannot be used with other gas types.

What are the physical dimensions and outlet thread for mounting?

The body diameter is 3.64 in and the outlet uses a 5/8 in.-18 RH thread for hose or manifold attachment.

How is the regulator installed and what step is often missed?

Thread the CGA-320 nut onto the cylinder valve, tighten with a wrench, then open the valve slowly; skipping the slow-open step can damage the stainless-steel diaphragm.
