Connect two tanks to your existing regulator
Individual shutoff valves for each tank

Atlas Knife & Tool’s Dual Tank Adapter lets you run propane tanks in true parallel so both cylinders share the vaporization load. That means each tank chills more slowly, maintains higher pressure, and delays freeze-up — exactly the behavior shown in the chart above. Whether you’re welding, forging, or firing a high-output burner, this keeps your heat consistent longer and reduces “soft flame” interruptions.

Once connected, open your tank very slowly to prevent tripping the safety valve in modern tanks
If safety valve trips when opening the tank, close the tank and wait for the click before opening again.
