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

Perhaps its too early for five stars, since Ive only gone tubeless on my mountain bike for about a month. But this stuff really works for me. I ride on a trail with lots of gravel, sharp rocks and fallen branches. After sealing punctures on both my front and back tires, i pump up the 29x3 tires to 30psi and they just keep rolling.

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.

Works great

It was really easy to clean this out of tires, making tire replacement really easy. The sealend works amazing and lasts long aswell

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

This is what Ive used on the Great Divide Mountain Bike Route and never had a flat. I guess another sealant could have worked but I know this one did work. It tests well in reviews and I trust it.

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.

Never disappoints!

Fat bike

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.
