The longer lasting tubeless sealant.

For their Endurance Tubeless Sealant, Orange Seal concocted a mixture that lasts at least twice as long as standard sealant while still using their combination of premium latex and what they have dubbed "nanites". These nanites are solid particles of various sizes that work with the latex to quickly fill holes up to 1/8” in size and slices up to 1/4” for robust protection when you're far from home. 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. Since cycling can take you to many different locales, this sealant is also designed to work at varying altitudes and in diverse climates.

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.

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.

Works better than most

Have used others in past but Orange seems to seal better. Have used in Hillybilly race with no issues. It does dry up after a few months and needs to be topped off in tires

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.
