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

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.

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.

Use a third less than recommended. My 29x3.0 tires only needed around half. Seals instantly, 1400 trail miles and no flats.

Been using Stans race day almost exclusively in (700x28 GP5000 70psi) as it is the only thing that seems to actually work, but tried this in the hope that it would laster longer than the 4 weeks of the Stans. It lasts longer but just doesnt seal most of the time, I dont get it, everybody raves about the long life, but if it cant fix the hole like ever, then it really doesnt matter how long it lasts.

This sealant is useless. Send it back to the orange julius store. Figured I would try it since it is a little cheaper than Stans but back to Stans it is.

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

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 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.

Good stuff
