Designed for high-pressure tires the Flatematic High pressure automatic tire inflator can precisely inflate up to 232 psi. This one outlet automatic tire inflator once connected to the tire will automatically start inflation or deflation. Its clip-on chuck secures and makes tire inflation more productive by allowing you to work away from the tireThe Flatematic High pressure is also nitrogen compatible and is equipped with a N2 purge cycle function which can perform up to 5 cycles. Each cycle will inflate with nitrogen up to the selected pressure then deflate to 5 psi then inflate again to the final selected pressure. For every purge cycle performed, the nitrogen purity in the tire increases.*Air compressor required Important: compressed air contains water and oil, use proper air filter between the source and device. Failure to do so will void the warranty.
