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

The only sealant I use. Longer lasting than most. Good puncture protection for small to medium holes.

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 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.

I've primarily used Orange seal on my bike. Not for any reason, I am new to the whole MTB scene... It was just one of the first better reviewed sealant I've seen. My impressions of this bottle is VERY good. See, I bought brand new tires and immediately caught a hole in them. The stock sealant from the bike shop install wasn't able to cut it, the hole was too large for that. But I didn't feel like buying new tires are the time either so I patched the hole myself and bought new sealant ( this stuff ). The tubeless install went flawlessly. This sealant works. After a couple of weeks though I started losing air pressure. At the end of a ride my tire would eventually be really flat. I figured it was the patch work... patches are supposed to just be temporary after all. But just for the heck of it I topped off my sealant because I didn't hear any leaking. Just like that problem solved. A few more weeks and a couple more rides later and my tire still has the same amount of air in it as it did before. This stuff just works. Time will tell on if it can seal tire damage but in terms of a tubeless tire install and sealing, the sealant just works.

Give the 29" 2. 25. 1-1.5 oz every 6 months. Never dry up / go flat . Real endurance,best I've used so far . Recommended

I have done 4 tires so far, 29" x 2.6 , 26" x 4" fat bike and 2 ea. 700c gravel tires. One gravel tire and the fat bike tire both needed several inflates and rides before holding, now they work good. Zero flats so far ( real reason for going tubeless in the first place) If they don't dry completely out and fail during the winter, I will wish I gave a 5 star.

Can not complain - have been using the same bottle of sealant for 3 years now and still use. only have replaced after tire punctures, sealant does not need to be replaced as often as recommended, would only replace if losing air. no complaints.

The best sealant out there. Stops everything!
