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

Great product

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.

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!

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.

Just broke the bead on my tires for the first time since going tubeless in early April. To be fair, this is my 1st time trying tubeless, Id avoided it due to concerns about it being a mess to swap tires... I also didnt get (that I could see anyway) any punctures to really test it out, but then Ive never gotten many flats anyway, part of why I never saw the need to go tubeless. My rear tire had a film of latex (I guess its latex?) but did still have liquid, maybe an ounce or so. The front lacked any film, and only had maybe half an ounce of watery orange liquid... thats probably on me. Interestingly enough, I noticed the rear losing air more so than the front, but that could be due to my narrower rear tire and the higher PSI I keep it at. Either way, both tires stayed rideable for at least a week between top-offs. Cleaning the dried film out of my rear tire was pretty quick & painless, other than right on the beads it peeled off in huge sheets. So while I cant vouch for its puncture sealing abilities, it does a good job of keeping tires airtight otherwise, and seems like the 6+ month lifespan is right on. Which is what I was more concerned about anyway, personally... I didnt want dismount, clean, and reseal tires to be something I did a couple times a season. I killed what was left of my original 8oz bottle on this use, and have a 2nd on the way so I can add a little more and have some on hand. While I never really had major issues with tubes, this stuff is convenient enough that I had no thoughts of going back.

Fat bike

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.

This is the best sealant for for east coast riding.

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.

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
