Endurance Formula Tubeless Bike Tire Sealant | Long Lasting, Fast Sealing | for MTB, Road, CX and Gravel Bicycle Tires

This tire sealant has worked pretty well so far. I normally use another top brand yet opted for this one since I needed sealant for the next day. The Orange Seal arrived in time for me to top off my newly installed tire. I am happy with the size of the bottle since I can add whenever I need to refill. It was easy to apply since the sealant did not seem thick. I have tried others that was difficult to add through the valve yet this one was perfect. I haven't had issues or puncture yet, that I know of. If I have, then the sealant is working great! I think it was a great value for me!

I have been using this version for a while and it is my go-to sealant now. Always works. Doesn’t dry out quickly. Easy to top off with the injector that comes with it.

The best!! No more flats. Great product

works well but does not last very long, maybe 3 months tops

I got a sharp puncture right through the sidewall of my road tubeless tire — sealant was spraying out, and I thought it was over. But Orange Seal Endurance actually sealed it after a couple wheel spins! I was able to finish the ride and it’s been holding ever since. Highly recommend this formula — long lasting, reliable, and works even on sidewall gashes most sealants can’t handle. I’ll never use anything else.

So far so good.... used this for both of my tires on my electric scooter! Pulled out huge goat heads as well as a peice of wire with no issue's. Best stuff i used to date!

I used the Orange seal last year for my first set of tubeless tires. I never had any issues or any flats. When I removed the tires after 3500 miles to replace them I could see where there had been a few punctures but orange seal had plugged up the potential flats. I’m staying with Orange seal for my tubeless tires.

Unlike another leading brand, this stuff doesn't dry up in the re-closed bottle faster than I use it. That difference makes my real unit cost lower even if I nominally pay a little more for the bottle. It also manages to stay sealed at skinny tire road bike pressure, whereas many sealants seem to fail above ~40psi. Fine for some types of riding and the tires that go with them, but I prefer to run even my gravel bike above that.

Best sealant I have used by far. Seals holes in minutes, even while riding. Bigger holes can be plugged if required.

Good stuff and not overpriced and does not smell like cheap bulb gum..... M___off ! ;)

És el único que uso después de probarlos todos. Imprescindible en verano, aguanta todo el verano sin descomponerse

Do not pay this price for an 8 oz bottle. You can get double the amount for less than the price of this at any proper online bike retailers. Nothing wrong with the product itself though. Orange sealant does the job. It's just normally much cheaper than this complete ripoff.

..but quite expensive for what it is. Product info is a bit silly, though: "Adults, Unisex, Orange". The liquid isn't even orange and I do believe you can use this on a kids bike. And Unisex, what's up with that? I think Non-Binary would be more appropriate for this tubeless sealant.
