I just bought 30 food grade CO2 cartridges and found out the hard way that they don't work on bike inflater adapters. The neck is slightly oversize such that it doesn't fit. Has anybody modified either the CO2 cartridge by filing it down or maybe opening up the adapter fitting so, that the neck will fit in?
I'm not too sure I want to start filing down the neck of the CO2 because if I file down too low I've got a potential rocket on my hands.
I thought about removing the threads in the head of the adapter because it's dual purpose for threaded and non-threaded cartridges and then only be able to use non-threaded cartridges (which I prefer)
And yes it's too late to return the cartridges.
