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. This version includes Orange Seal's Twist Lock Injection System for quickly and neatly installing sealant through Presta valve stems. (Requires valves with removable cores.)

8 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.

great stuff

So glad I switched over to tubeless. This stuff works super well. Had one puncture recently, and this stuffed sealed it really quickly. Very satisfied. Only thing, is, it is very hard to measure how much you are putting in.

The new Sealant to beat...

I recently read a MTB Action article that thoroughly tested every known sealant on the market today. Orange Seal won the testing and beat the competition hands-down. On top of it all, Orange Seal's Endurance formula is very competitively priced and that's what I call Progress!

Used as a preventative on my tubulars

The product was easy to use and really works on small punctures . I was able to ride over 1200 miles on my same tires.

Works OK, but...

I installed a Schwalbe Pro One on Easton R90SL tubeless rims (yes, a road bike) and sealed them with Orange seal. On my 3rd ride I got a puncture that was just shy of 14 inch. The sealant sealed the holed but not before the tire was down to about 20 psi. I tried pumping it up to get the remaining 9 miles home. It would hold no more than about 40 or 50 psi. The good news is that it did get me home. The bad news is that the tire was no good after that as it would not hold a decent amount of air, despite the use of the sealant.
