Nope, not my technique. Each one has worked for me when I first get it. After they sit in the bag for a year or two it seems like the seals get gummy and then don't seal when I screw the CO2 cartridge into the inflator. Or in the case of the Blackburn inflator the head mechanism became jammed up with something and wouldn't depress to open the valve. Maybe I need to keep my saddle bags and camelbacks cleaner, or put my inflator inside a ziplock.
