CGA320 Soda Machine blue Co2 Bottle Cylinder Refill Adapter Hose,For Refill blue Co2 Tank Bottle(CGA320 to TR21-4, Dual Valve With Gauge) (36In)

I bought this as a replacement for an earlier setup that used a custom needle valve to slowly start filling. The earlier one's seals failed with no way to replace them. I was worried that the ball valves on this one would make it hard to control the fill rate to start. Not a problem, I'm able to start slowly and increase the fill rate quickly. The refill connector's adjustable pin makes attaching and removing cylinders a breeze. The custom parts are well made and the valves and high pressure hose appear to be high quality. Having spare seals is nice touch as well.

This works really well. I fear that the hose may snap under pressure some day. I always shut off the main tank valve and release the residual pressure between the main tank and the two ball valves between fills. I wish there were some guidance on the number of pressurization cycles I should replace the hose after.

Good quality but will not charge tank

This item works perfectly. Hooks up right to my tank refills. The blue SodaStream containers flawlessly.

Bought this to fill up my sodastream twist on 1l tanks with a 20lb tank. It works/fits really well no complaints, and it even comes with spare washers to ensure there's no leakage. The instructions are a bit confusing but a quick YouTube tutorial cleared up any confusion.

Works good. More complicated than necessary though. Eeveryone that knows anything about CO2 knows that a pressure gauge is worthless with liquid Co2. It turns to gas at the same pressure so the gauge only works when you are out of liquid. Why confuse people?

The components are high quality except for the gauge which seems to be of low quality. I followed the instructions, and it worked just fine. After the initial, cost this will save a lot of money on co2 refills.

This will not refill a blue soda stream CO2 bottle
