Description
49-CO2 Double Stage Double Gauge Carbon Dioxide Gas Pressure Regulator
The 49-CO2 Double Stage Double Gauge Carbon Dioxide Gas Pressure Regulator is designed for stable and controlled regulation of Carbon Dioxide (CO₂) gas from high-pressure gas cylinders to the required working pressure.
Its double-stage pressure reduction system reduces the cylinder pressure in two stages, helping maintain a more consistent outlet pressure as the cylinder pressure changes during operation. The double gauge configuration allows the operator to monitor both the cylinder pressure and the regulated delivery pressure.
Designed for professional welding, fabrication, and industrial gas applications, the 49-CO2 CO₂ Regulator provides smooth pressure adjustment, stable gas delivery, and dependable performance where accurate Carbon Dioxide gas pressure control is required.

Advantages of Double Stage Regulation
The double-stage design provides improved pressure stability compared with a conventional single-stage regulator. Gas pressure is reduced progressively through two regulating stages, helping to:
- Maintain a more consistent outlet pressure
- Reduce pressure variations during operation
- Improve control of CO₂ gas delivery
- Reduce the need for frequent pressure adjustment
- Provide stable performance during extended use
- Support professional welding and industrial applications
How to Use
Before installation, make sure the Carbon Dioxide cylinder valve is completely closed.
Connect the 49-CO2 Carbon Dioxide Gas Pressure Regulator securely to the cylinder using the correct CO₂-compatible connection. Keep the pressure adjustment mechanism in the released position before opening the cylinder valve.
Slowly open the CO₂ cylinder valve and observe the inlet pressure gauge. Gradually adjust the regulator until the required working pressure is displayed on the delivery pressure gauge.
Check all connections for leakage using an approved gas leak-testing method before starting operation.
After completing the work, close the cylinder valve, safely release the remaining downstream pressure, and return the regulator adjustment mechanism to the released position.
Safety Note: Carbon Dioxide is non-flammable but can displace Oxygen in confined or poorly ventilated areas. Always use CO₂ equipment in adequately ventilated environments and follow proper compressed gas handling procedures.
