Made of stainless steel, firmer and more durable, so you can make your drinks more easily carbonated
With this cap, you can easily fill an old PET bottle with cold liquid of your choice and carbonate by connecting the isolator switch of your gas ball lock.
With it, you can make your own soda water, carbonate beer or even your own alcohol-free drinks.
It fits most PET bottles with soft drinks, injected CO2 into the bottle and produces carbonated dioxide.
The carbonation cap is a highly effective way to provide and maintain carbonated drinks for longer periods of time.
