STAYFILL keeps your wheels ready to roll
StayFill® is a proprietary gas blend that keeps tires inflated for over a year. The actual gas mixture is a trade secret, but we can tell you that StayFill’s molecules are 2-3 times larger than CO2 or air molecules. StayFill’s larger molecules do not pass through tire walls like CO2 or air molecules. A StayFill® cartridge is filled to approximately 320 psi @ 70℃. This compares to a CO2 cartridge, which is filled closer to 830 psi @ 70℃.
StayFill® makes sure your tires are ready to go when you are. No more pumping tires when you or your kids want to go on a bike ride or use equipment or tow a trailer. StayFill® eliminates the hassle and frustration of pumping tires and offers the convenience of ready-to-go tires.
StayFill® can be used with CO2 or air. However, concentrations in excess of 14 psig may result in some CO2 or air leaking out thereby requiring a top off with StayFill®.
StayFill® is non-toxic, non-flammable, and non-ozone depleting. However, StayFill® is packaged under pressure (approximately 320 psi @ 70℃) and can be dangerous if not handled properly.
As of this writing, traveling by commercial aircraft with StayFill® cartridges is NOT acceptable according to the United States Transportation Security Administration (TSA) website (www.tsa.gov). Before traveling with StayFill® cartridges, it is strongly advised that you consult your local airline, airport and/or travel agent, and check the TSA website for any changes that may have occurred since this writing.
StayFill® is inert and will not harm your tires, ever.
StayFill®, like all gases, changes its pressure with changes in temperature. When temperatures drop, the pressure will drop. This means you may have to top off your tires with more StayFill® when outside temperatures drop. Conversely, if you top off or fill your tires when it is cold, you may have to let some StayFill® out of the tires when it gets warm again to get back to the optimum pressure. A StayFill® cartridge is filled to approximately 320 psi @ 70℃. This compares to a CO2 cartridge, which is filled closer to 830 psig @ 70℃.
Great. StayFill® will stay where it is supposed to — in your tires. The thinner latex tire walls are perfect for StayFill®. While tires filled with CO2 or air will see extremely high leak rates, StayFill® will not pass through the latex tire walls.
StayFill® is heavier than CO2 or air but the actual amount will depend on the size of the tube and fill pressures. In our tests using high-pressure road tires, StayFill® added approximately 3 ounces more than CO2 when filling both tires. For the weight conscious, this may be unacceptable, but for most of us, StayFill® weighs less than one of those energy bars you might take on a ride.
StayFill® can be used in basketballs, footballs, soccer balls, inflatable pool toys, baby joggers, bicycle air struts, wheelchairs, ATVs, and more. Please write us and let us know about other uses for StayFill®. We’d love to hear about it.
