This is instruction for an item sold by me on Etsy

2 in 1 adapter. You can use it to connect external source of propellant (CO2 from SodaStream tank or compressed air from PCP tank)
Disassembly
Remove CO2 cartridge pusher.
Assembly
Install external tank adapter
The end of the adapter should fit nicely inside valve port
Hand tight the adapter and don't use too much force. In case of any leakage, screw it a little more.
