Stan's Tubeless Tire Sealant Injector Description: Stan's Tubeless Tire Sealant Injector works to fill tubeless tires with sealant faster and with less mess using a practical syringe design and adaptive valve fitting. A generously sized, graduated cylinder fills with 150ml of sealant to help service high-volume tubeless mountain, gravel, or road tires in a single fill, saving time and effort. Avoid messes when handling the task of injecting well-mixed sealant by way of the top-filling cylinder design which features a unique air-relief channel that works with a cross slit valve fitting to negate excess air pressure for predictable injection. Functionality with more bikes is assured by the press fit valve adapter that connects to both Presta and Schrader valves without the need for additional threading or parts. Features: Top-fill injector for tubeless tire sealant Patent-pending drip free design features large 150ml capacity; ideal when filling larger volume tires in a single fill Included valve adapter fits directly on both Presta and Schrader valve stems Top-filling design, cross-slit valve fitting, and air-relief channel eliminates potential messes when used with well-shaken sealant Included hang-plug allows syringe to store vertically, preventing drips when not in use Note: For use with Stan's Original Tubeless Sealant only, not compatible with Stan's Race Day Tubeless Sealant formula Specifications: Capacity: 150ml Compatibility: Presta or Schrader
