The best CO2 inflator we have NOW works with more CO2 cartridge sizes (12 gram threaded, 16 gram threaded & non-threaded, 20 gram threaded, 25 gram threaded). From our EZ Connect Technology to our built in all weather nozzle cover, the new Proflate Elite is loaded with features that makes inflation safer and easier. Simply drop the cartridge into the cup (or screw cartridge into the head of inflator), attach the head, press onto valve stem, pull trigger and begin controllable inflation. Easy enough to use with one hand, it will get your tire up to desired pressure in seconds. You’ll be back to your ride in no time.
