Unthreaded 8g c02 capsules

[Libigage]

Hi, I have a load of unthreaded 8g c02 capsules in my shed from an old soda water dispenser. Does anyone know if there is an adapter or some way of getting the gas out into a keg. Ideally I want to connect it to a sodastream regulator so that when I've used them all I can go back to the sodastream canister and 16g threaded capsules

You could look for a cycling tool, I used to have a 16g one that took unthreaded caps, I then sawed a used cap in half(ish) to convert it to work for 8g caps that I ended up with a load of. This then went out to a schrader valve. This wasn't for brewing so not sure what would go schrader to keg but must be something?

Here is my Heath Robinson contraption that I knocked up to use loads of the 8g bulbs I had left over from my pressure barrel days. I used it to inject CO2 into my brewzilla when kettle souring.

Its an old pressure barrel bulb injector, secured to silicone hose and a fitting, you could use a grey disconnect for a corny. Just insert the bulb, twist and pierce, and the gas shoots out the other end. No idea if I'm losing a load of gas in the process but it seemed to work.
