Our 8-88g threaded CO₂ cartridges are built for North American wholesalers who need reliable, certified cylinders without the back-and-forth. We cover five sizes: 8g, 12g, 16g, 33g, and 88g. All of them use the standard M16x1.5 thread, so they fit most soda makers, life vests, airsoft guns, paintball markers, and bike tire inflators.
The 88g is our commercial workhorse. It holds nearly seven times the gas of a 12g cartridge, which means fewer swaps and less downtime for your B2B customers. The 33g is specifically sized for life vests and airbag vests-this segment has grown over 80% year-on-year in the US. If you supply safety gear, this is the size to stock.
Every cartridge is DOT certified. The DOT mark is permanently etched, not a sticker. We learned that lesson the hard way years ago when a German shipment got held at customs. Since then, we've etched every cylinder. For food-grade applications, we use FDA-compliant CO₂ and EPDM seals. TPED certification is available if you ship to Europe.
We pack each carton with desiccant and wrap every pallet in moisture barrier film. Ocean shipping takes a month; rubber seals age in heat. This packaging keeps them fresh. We include third-party test reports with every batch. UN1013 Class 2.2 documents are ready for customs.
We run our own factory in Dongguan, not a trading desk. Monthly capacity is around 500,000 pieces. OEM and ODM are welcome-custom weight, packaging, and logo. If you want to test quality first, we'll send samples. Contact us and we'll reply within 24 hours.
