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

This sealant is easy to install and is not as gloopy or smelly as some others I use in road and MTB tires.

Works like its suppose to and at a really good price. This one does not have the tube for dispensing fyi. So you will need some small tubing in order to get the fluid into the tire through the valve stem.

Been running this on families bikes! Lasts a solid yr. See no need to replace it...….But, I do Just in case ;-) Comes out and able to clean out of tires much easier than Stans. Ugg that Stans is awful to clean out of tire. Although, havent had a puncture large enough to notice if its had to work yet ;-) Fingers crossed.

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!

It is a good sealant on road bike wheels. I was using stans on MTB for years without any problem. When the tubeless trends on roadies I add stans as well but it seems not good at all. Then I purchased this orange sealant and the flat problem never stopped me again. I will recommend this one.

I use it in my tubeless gravel bike. Has saved me on multiple occasions. I even had a cut in the sidewall of a tire that sealed and lasted about 500 miles. Only reason it didn’t last longer is I replaced the tires because they were bald

Setting up tubeless tires can be messy. This stuff is great in that context. Its easy to clean up, easy to use and is eco-friendly.

Never disappoints!

I had a tire that didnt look worn. Only had 400 miles of use. But Id run out of Stans Race Sealant, so I mounted it with regular Stans because thats what I had on hand. And at 400 miles, that thing turned into a sealant sprinkler. Innumerable tiny holes would spray sealant all over on my commute, then seem to seal -- only to start spraying again next time I tried to ride. After a few days of that, and topping off with more Stans, I thought I was going to have to replace the tire even though it didnt look worn. I still hadnt been able to get Stans Race at any reasonable price, though, so I ordered a bottle of this stuff hoping to actually get a lasting seal on those pinholes. It worked. Ive got 900 miles on that tire now and it hasnt shown any sign those pinholes exist, or of any other trouble, since I first added this sealant to the tire.

Used this on a tire that would not seal even though the bead was set. This was NOT a tubeless tire, but rather a wire bead tire. When I tried the strap around the tire trick to force a seal it wouldnt take. I thought, what the heck, let me try the sealant. Did the same trick and literally saw sealant seeping out of multiple rim/tire interfaces on both sides of the tire. I kept pumping for a few minutes and suddenly it started to inflate. I removed the strap and successfully got the tire up to pressure. After cleaning off the sealant mess I decided to test it out. I went down to a low pressure (tire rated 30PSI min, I did 15PSI) and took the bike on a tough gravel hill climb. It did excellently and the pressure was the same after the ride! Unfortunately I tried to add more sealant and couldnt get the seal to stick this time. Perhaps I kinked the wire bead. Dunno. But I was convinced that if this sealant could seal a tire with that much leaking air AND handle a rough ride on a NON tubeless tire set up for tubeless, then it should do great on a real tubeless tire. Best of luck to you
