The CO2 inflator I used to carry had a sleeve that screwed on for the cartridge. I didn't think about the cold part but it also allowed use of either smooth or threaded cartridges, or the 12 gram cartridges from the bb gun aisle. It had a Slime brand sticker on it but I've seen the same one with other stickers
