So today I got my 1x2kg CO2 bottle filled. The other one had a leak when ever I connected the regulator the CO2 would come spraying out over my hand. It leaked here: So when I addressed this with the refill company they said to me that they had checked it and assure me that there is no issue with the valve at question. So this afternoon I decided to test both just incase, guess what both are now leaking at that valve at the top of the CO2 handle. Could it be that the following seal on the regulator is not sealing anymore as it is supposed to: My issue is if it was the seal it wouldn't be leaking at the top where the canisters valve is located at the top? Any advise would be greatly appreciated?
