Orange Seal's 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 1/8” in size and slices up to 1/4”. 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.

16 oz bottle. Orange Seal recommends using 1 - 2 oz. of sealant for use with road tires and 4 oz for 29” MTB tires. Compatible with tubeless tires, inner tubes, and tubular tires. Claimed sealant life averages 60 - 120 days before needing replacement.

works great

My first foray into tubeless was with 700c gravel bike tires. Love it. I'll never go back. Orange seal has treated me great. No complaints.

Long lasting peace of mind.

Rode 20 miles with a 58 inch screw in the tire and this stuff kept enough air in tire to make it home. Works great for 5 month then slowly loses it's leak stopping power. I use the removable valve stems to put it in the tire, this brand does not plug the valve stem and flows in with just squeezing the already beaded tire. I have used this brand for 3 years and have used probably 4 quarts during this time for MTB, gravel, and road.
