Orange Seals Endurance Tubeless Sealant is designed to last at least twice as long as standard tubeless sealant while still utilizing a combination of premium latex and nanite solid particles that work to quickly fill holes up to 18 in size and slices up to 14. Orange Seal’s recipe is formulated to be as light as possible to keep rotational weight to a minimum and is made from eco-friendly biodegradable ingredients. This version includes Orange Seals Twist Lock Injection System for quickly and neatly installing sealant through Presta valve stems. Requires valves with removable cores.
