Orange Seal Endurance Formula Bicycle Tire Sealant for Road, Mountain Bike, CX, BMX, and Tri Bikes (8oz)

After reading about different tubeless tire sealants I decided on Orange sealant. A lot of sealants react to C02, but not this one. I already had about 4 punctures and it sealed everyone of them. Excellent choice.

I love this stuff. Lasted almost a year on my Giant TRX1 wheelset with Schwalbe Nobby Nics front and rear. I dont know if Ive had a puncture yet so I cant comment on that. Its also the only sealant Ive used so take this review with a grain of salt. :)

Over the last 10 years Ive tried dozens of different brands of tubeless tire sealants, including the most popular S brand, as well as others and I will say that the best sealing, easy-to-work-with, long-lasting sealant of the bunch is Orangeseal. You wont find any gimmicks here like rainbow sparkle flakes or UV glow - Orangeseal is just a sealant that works. I put 2 ounces in each 27.5 tire of my mountain bike, and that usually lasts about half a year before I notice the sealant level drop (I check the level once a month). When I have to swap tires, the old sealant is simply a layer of coating along the inside of the tire - it doesnt clump up into chunks, and it doesnt create messy spiderwebs of dry sealant that takes hours to clean up (unlike the most common S brand). Ever since I switched to Orangseal, I cant remember the last time I had a real flat tire. This is the good stuff, for sure!

This is the best sealant for for east coast riding.

Good stuff

When I worked at a shop we used this stuff on everything. We had a lot more issues with Stans. I personally always put this in my tires. I can get this stuff to set up on non tubeless tires.

Worked well! Old sealant was dry, just added 4oz in each tire. Will buy again

Works better than Stanz. Do not form polimer meteor inside tire. Have longer life inside tire.

Just broke the bead on my tires for the first time since going tubeless in early April. To be fair, this is my 1st time trying tubeless, Id avoided it due to concerns about it being a mess to swap tires... I also didnt get (that I could see anyway) any punctures to really test it out, but then Ive never gotten many flats anyway, part of why I never saw the need to go tubeless. My rear tire had a film of latex (I guess its latex?) but did still have liquid, maybe an ounce or so. The front lacked any film, and only had maybe half an ounce of watery orange liquid... thats probably on me. Interestingly enough, I noticed the rear losing air more so than the front, but that could be due to my narrower rear tire and the higher PSI I keep it at. Either way, both tires stayed rideable for at least a week between top-offs. Cleaning the dried film out of my rear tire was pretty quick & painless, other than right on the beads it peeled off in huge sheets. So while I cant vouch for its puncture sealing abilities, it does a good job of keeping tires airtight otherwise, and seems like the 6+ month lifespan is right on. Which is what I was more concerned about anyway, personally... I didnt want dismount, clean, and reseal tires to be something I did a couple times a season. I killed what was left of my original 8oz bottle on this use, and have a 2nd on the way so I can add a little more and have some on hand. While I never really had major issues with tubes, this stuff is convenient enough that I had no thoughts of going back.

The product gets a 5 Star rating, absolutely the best you can buy! But, be careful of the seller. I received my Orange Seal Endurance on October 5, 2021. The expiration date on the bottle is July 19, 2021. :-(
