UNIVERSAL COMPATIBILITY: Standard 3/8-24 thread fits virtually all CO2 inflators and inflator heads designed for threaded CO2 cartridges. Works for bikes and other 3/8-24 threaded-cartridge devices. Exception: some inflators with integrated cartridge storage are sized for 16g cartridge diameter only.
BIKE SHOP QUALITY: Same high-quality threaded cartridges you’d buy at a local bike shop—available in value packs. Premium rolled threads, flat sealing surface, consistent CO2 volume.
HANDHELD + PORTABLE INFLATION: Compact, lightweight refills that fit in a saddle bag or tool kit for on-the-go inflation. Fast tire inflation for roadside flats—no pumping, no waiting (inflator head not included).
MTB & ROAD BIKE CAPACITY: 16g is best for road and smaller-volume tires; 25g provides more air for larger MTB/high-volume tires. Both sizes use the same 3/8-24 threaded connection (Note: 25g may not fit inside integrated cartridge storage housings found on some inflators)
SAFETY & EXPIRATION: Pressurized CO2—store cool and dry; do not leave in a hot car or direct sunlight. May rupture if heated beyond 120°F. Discharge can cause cold-burn—use gloves and eye protection. Cartridges do not expire or “leak out” over time when stored unpunctured.
PURE CO2 + RECYCLABLE STEEL: 99.99% pure CO2 with no additives or preservatives. Single-use alloy steel cartridge is recyclable where accepted; not refillable. Not certified for food use.
