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

Orange Seal Endurance sealant is my favorite sealant for my tubeless mountain bike tires. Can get 4 tires fully filled with the 20oz bottle or more if just topping off. Stays liquid for long time without solidifying and have never had a flat

Good quality product

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.

I found out about Orange Seal after much, much aggravation with Stan's. When I used Stan's, my tires bled constantly from the sidewall. Specialized told me "we recommend not using Stan's as it has corrosive properties not compatible with our tires". Kenda - ate through the sidewalls. Then one day out on a brand new $60 tire, I got a cut about 1/4" long. Already really pissed at how much MTB tires cost, cutting a brand new one like that sent me into orbit. I took the tire apart, cleaned it extensively, put a patch on the inside of my tire where the cut was (I'm running tubeless), let it dry. Tested the hold by hand before putting the tire back together on the bike. I really squeezed & pushed it, the patch seemed solid. Put Stan's in, aired up the tire. Checked again - yep, holding air. Loaded up & drove off to hit the trail. Get on the trail and 15 minutes into my ride, the tire goes flat. Cussing like a sailor, I walked back to my truck, threw my stuff in & went back home. Took the tire apart, and the patch is laying in the tire not glued to it. Stan's ate the glue off. Refusing to give in to tossing a $60 tire in the trash, I went to a couple bike shops explaining what had happened. One shop recommended Orange Seal, saying that's what they use in the shop. I once again, went through the process of patching the cut in my new tire. Put it all back together, checking the air constantly for any sign of loss. Went on my ride. It held! In fact, it held so well that I rode that tire until the tread was gone with the patch STILL holding! I've been sold on Orange Seal ever since. I'll never use Stan's again. It costs a couple bucks more which I didn't like, but it does work. I think both brands are about 200% profit to the manufacturer which is why I gave it only 3 stars on Value for Money, but if you have to pay, might as well pay for something that works.

I’ve always used this sealant and never been disappointed. Not only does it easily seal the small punctures caused by glass, I was 20 miles out on the trail and after initially loosing a bit of sealant, it plugged a good gash in my tire and got me home. The price is reasonable as well.

Orange Seal works great. I bought after using Trek brand and Orange Seal did the job Trek couldn't do. Recommend 100%

Two oz for my road tires and it’s sealed. No leaks! No mess! So far so good on a few rides and no need to add air.

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 ! ;)

Tried couple of times to seal my tube - no success. The liquid is everywhere.

waaaaaay better than stans!

I’ve tried a few different tubeless sealants over the years, but Orange Seal Endurance is easily the best of the lot. It seals punctures faster and more reliably than anything else I’ve used, and it stays liquid for much longer. I can go months without topping up, and it still seals small holes instantly on the trail. It also coats the inside of the tyre evenly, so you don’t get those annoying dry clumps you get with cheaper sealants. If you want a sealant that you can trust to actually do its job when you’re miles from home, this is the one. Absolutely worth it.
