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

Works great

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.

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.

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.

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

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.

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

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!

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.
