The air release is fully controlled by a diaphragm valve and a push button trigger, providing maximum precision during operation. The Automatic Bead Seater also comes with a fully certified storage tank with a pressure gauge and safety valve to prevent overpressure. This innovative product incorporates a host of useful features that make it superior to any other bead holder on the market. Automatic bead holders are designed to displace air into the void inside the tire, effortlessly pressing the bead onto the rim. This feature takes the frustration out of manual installation and makes it quick and easy. In addition, the quick exhaust valve ensures that the bead seat is easy to use and saves effort.
