Stan's NoTubes Injector

While tire sealant has changed the way we ride, it can be a hassle to install. The Stan's NoTubes Injector aims to change that. The graduated, two ounce injector makes application of sealant simple, with no mess or waste. You can use it to transfer sealant from one tire to another, or use it to inject sealant through the valve stem. It features a dual thread adapter that fits both presta and Schrader valves.
