1. This product is a bicycle CO2 inflator valve adapter designed for rapid tire inflation using high-pressure CO2 cartridges. It features automatic compatibility with both Presta and Schrader valves and does not include the CO2 cartridge, which must be purchased separately. 2.

Protective Foam Sleeve: The flexible sponge sleeve helps prevent frostbite on fingers caused by the rapid CO2 gas release, which can form frost on the cartridge surface. 4. Durable Aluminum Alloy Construction: The valve head is made from aluminum alloy, designed to withstand high pressure and repeated use without damage. 5. 360-Degree Rotation Mechanism: The rotating design enables easy screwing onto the valve, reducing effort during inflation.
