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

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.

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.

Fat bike

Works great

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

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.

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!

Definitely works well and holds air like a champ. I would highly recommend the Sealant to anybody looking for something durable and for us free. Change about every 60 days and you’re good to go.

Ever since I switched to tubeless tire, I have had numerous tire punctures (maybe 10?). 9 of out the 10 times, it just sealed itself without me doing anything other than getting off the bike and spin the tire for couple of mins. It does got messy when the sealant sprayed everywhere but it is also beautiful that it usually stops after a few mins. I use the Orange sealant exclusively. I think the recommendation is to change it every quarter, but I found that I can stretch it to 9 months and the sealant is still ok.
