Lasting twice as long as traditional tubeless sealant, the Orange Seal Endurance Tubeless Sealant with Twist Lock Applicator maximizes protection from thorny punctures and sidewall slices on the trail--all without drying up prematurely and requiring constant top-offs of sealant. This premium latex sealant features what Orange Seal refers to as nanites, which are solid particles of various shapes and sizes that quickly seal punctures and sidewall slices. This particular bottle of Endurance Sealant comes with a Twist Lock Applicator that quickly closes the flow of tire sealant, as well as an injector tube for adding Endurance Sealant directly into your removable valve core. Plus, it's formulated with biodegradable ingredients that aren't toxic to the surrounding environment.
