Victor 4000-0058 Two Stage Cylinder Regulator CGA 320
Two-stage cylinder regulator for carbon dioxide with CGA 320 inlet, 1 to 22 psi delivery range, and 1.97 in nickel-plated brass body
- Two-stage design delivers steady 1–22 psi outlet pressure
- CGA 320 inlet fits standard CO₂ cylinders directly
- Nickel-plated brass body resists corrosion in workshop use
- Stainless-steel diaphragm maintains calibration over long service life
- ETL and ISO listings confirm compliance with recognised safety standards
Purpose and fit
The Victor 4000-0058 is a two-stage cylinder regulator built for carbon dioxide service with a CGA 320 inlet connection. It suits workshops that need steady low-pressure delivery from high-pressure cylinders. Buyers who require a different gas service or a single-stage design will not be served by this model.
What the specification changes
Two-stage regulation reduces delivery-pressure drift as the cylinder empties, keeping output stable across the 1 to 22 psi range. The stainless-steel diaphragm and nickel-plated brass body resist corrosion from carbon dioxide, while the 1 31/32 in gauges show supply pressure up to 3,000 psi and working pressure at a glance.
Practical limits of the CGA 320 interface
The CGA 320 inlet locks this regulator to carbon dioxide cylinders rated for 3,000 psi maximum inlet pressure. The 1/4 in FNPT outlet fitting determines the downstream hose or manifold you can attach. The assembly is not rated for gases or pressures outside the listed carbon dioxide service.

Questions about this item
How often should the stainless-steel diaphragm on this two-stage regulator be inspected or replaced?
The stainless-steel diaphragm is built for long service; inspect it during routine cylinder changes and replace if you see cracking, distortion or leakage.
What pressure limit will the regulator hit first during extended welding runs?
Delivery pressure tops out at 22 psi, so that is the ceiling you reach before the 3,000 psi inlet gauge maxes out.
How much heat does the nickel-plated brass body generate when the regulator runs all day at 22 psi?
The brass body stays near ambient temperature because the regulator only reduces pressure; it does not produce heat during continuous flow.
