Argon and CO2 Flowmeter Regulator
The Radnor 64003041 is a single-stage flowmeter regulator designed for argon and carbon dioxide shielding gases. It mounts directly to a cylinder with a female 0.965-14 NGO inlet connection. The outlet uses a female 5/8-18 UNF fitting and delivers a maximum outlet pressure of 80 psig. Maximum flow rates reach 50 scfh for both supported gases.
Upgrade from basic single-gauge regulators
This unit combines pressure regulation and flow metering in one body, removing the need for a separate flowmeter on the gas line. The jump is worth it when a fabricator wants a single device that shows real-time flow for both argon and CO2 without swapping hardware between jobs. Single-stage construction keeps the design simple for steady supply pressures.
Suits MIG and TIG welders using argon or CO2
It suits welders who need a cylinder-mounted regulator with a 3,000 psig maximum inlet rating and direct-read flow indication up to 50 scfh. Buyers who require dual-stage pressure stability for long, uninterrupted runs or who need higher flow capacity should look at something else. The product carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item
What cylinder thread does the 0.965-14 NGO inlet fit?
The regulator mounts directly to a cylinder with a 0.965-14 NGO right-hand female thread. No adapter is required for standard Argon or CO2 cylinders.
How do I set the flow without over-pressuring the hose?
Open the cylinder valve slowly, then adjust the knob until the ball sits at the desired scfh mark — maximum 50 scfh for both gases. Do not exceed 80 psig outlet pressure.
When should I replace the flow tube or seals?
Replace the flow tube if the indicator ball sticks or reads inconsistently. Inspect the inlet and outlet seals each cylinder change; swap them if they show cracks or deformation.
