Easily install and maintain tubeless tires without the mess and without clogged valves. Do you want to work with tubeless systems and sealant worry-free? The revolutionary milKit tubeless valve system makes maintaining tubeless tires quick, easy, and clean: measure and refill the old sealant without releasing air from the tire; closed rubber flaps at the bottom of the valve prevent clogging from sealant. Simplified installation: the milKit valves hold air in the tire even without a screwed-in valve core, making it easier to inflate and add sealant—without the mess. This product, made in Germany, impresses with its high-quality, lightweight aluminum valves and elegant design featuring many smart details.
