Carbon dioxide CO2 cylinder filling made easy

cga 320 threadswhich thread can be refilled

CGA 320 Thread Definition

  • 0.825" by 14 threads per inch USA
  • 20mm x 5.5 threads per cm Metric Approximation
If you have a cylinder or CO2 bottle with CGA 320 defined threads like the ones on the right, you can refill the cylinder yourself conveniently at home for a fraction of the cost of having someone else fill it. If there is a pin valve in your gas cylinder such as paint ball, Soda Stream Gemini®, automatic transmission shifter cylinders and others, our fillers will work on all of them. Easy Instructions are provided with more detailed instructions with each kit.


Now refill all CO2 cylinders with or without a pin valve. Our equipment has been used for years in paint ball shops, Seltzer cylinder refilling centers, hot rod shops, and commercial soda manufacturers for filling cylinders (carbonators) and testing CO2 bulk deliveries. Our equipment will only work with cylinders which have CGA 320 threads. See Refilling Instructions.
