CO2 Connectors - Threaded vs Unthreaded
A discussion down there --v or up there --^ reminded me CO2 cartridges
come in a least two connectors, threaded and not. I've been caught by this. Why the difference? Who cam first? |

During my mis-spent childhood in the 1950's and 1960's, there were BB guns that all used non-threaded CO2 bottles. I didn't have one, but I did collect the spent CO2 cartridges to make small rockets that fit into aluminum cigar tubes. These had lead plugs and no threads. During the 1980's, there was a movement to remove lead from products which resulted in a redesign of the lead plug used on the non-threaded CO2 cartridges. I also noticed that the threaded bottles were lighter and available in a variety of sizes. BB guns continued to use non-threaded cartridges because that's what fits and works best for fitting into the gun. However, paintball guns used threaded because they needed larger CO2 cartridges. Drink carbonation devices tended to use proprietary cartridges and connectors, for obvious (profit based) reasons. Disclaimer: I'm not really an expert on the use and abuse of CO2 bottles, just an observer with a potentially faulty memory. You might ask the same question in a forum or newsgroup for BB and paintball gun. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Unthreaded CO2 cartridges are meant to be used in those devices that make carbonated water. I haven't seen a bicycle tire inflation tool that uses them. What's more, most of those fillers have a limited lifespan except for https://www.amazon.com/Genuine-Innov...ateway&sr=8-14 The Chinese seem to be making a machined aluminum version but I can't see why. |

Years and years ago there was a device consisting of a glass bottle with an attached CO2 cartridge, called a "siphon" was used to make carbonated water for mixing drinks. http://www.easywhip.com/soda-siphons.html I believe that the original CO2 cartridges were threadless. -- cheers, John B. |

Having a peer about I found https://www.amazon.com/POWERAXIS-Inf.../dp/B07Q2QDP6P Which is compatible with both threaded and unthreaded. Good idea imho as non threaded are cheap and easily available. |

Well, I see Amazon list threaded cartridges for 16 oz for $9.19 which seems pretty all right. By the way, different cartridges contain different amounts of CO2, which seems logical. See http://www.bikepro.com/products/pumps/pumpc02.html for a chart showing what each size cartridge will inflate which size tire to what pressure. Example: A 12 oz cartridge will inflate a 700-25c tire to 87 psi and a 700-28c tire to 84 psi. A 16 ox cartridge will inflate a 700-28c tire to 105psi, and a 700-32c tire to 90 psi -- cheers, John B. |

That's grams, not ounces.
And it's a pretty horrendous misuse of resources just to avoid pumping. |
