Orange Seal - Endurance Formula Tubeless Bike Tire Sealant | Long Lasting, Fast Sealing | for MTB, Road, CX and Gravel Bicycle Tires

Ive had this injected for close to a month now, and so far its worked perfectly. I initially put the same amount of sealant on both my Minions, but it seemed that my rear tire was leaking a tiny bit of air over the course of 4 days (ridden once), so I ended up putting in an additional 1.25 oz, which seems to have done the trick. Using this Along with the KOM sealant injector worked really well on the tubeless stems I purchased. Had no issues with clunks getting stuck in. Some people complain about a smell in other agents. Didnt notice anything with this, but I didnt go out of my way to smell it either. I havent noticed any punctures yet (hopefully I can just avoid those altogether) but Ill update my review in the future for anything I notice.

I switched from Stans to Orange Seal last season and I have been super happy with the change. Stans was making my tires really sticky on the inside, the sidewalls were sticking together really bad making it tough to add sealant (I normally pop a section of the bead off rather then inserting through the valve). I couldnt be happier with the Orange Seal. I pulled 5 goatheads out of my tire the other day. When I pulled the goatheads a little air escaped, I put my finger over the hole for a second and let it do its magic. Still running those tires, no leakage. You can see some wet spots where it seals, but honestly I dont know what we did before tubeless. With how many goatheads and cactus spines I hit in a season, I would be constantly changing tubes.

Use in all my bike tires

Its hard to believe that some foolish people refuse to accept the well documented proof that tubeless tires are far more reliable than tubes. Orange Seal has worked the best for me for over 5 years. All my mountain and road bike are now tubeless and I havent had a unsealable puncture in literally thousands of road and mountain miles. I ride primarily in western Colorado, Utah, and the Big Island of Hawaii. All well known for being hard on bike tires. Tubes are outdated old school tech that has suffered the same fate as rim brakes and steel frames. The nay sayers all love to tell stories of some poor soul the had a sidewall gash and got covered with sealant. They tried to fix it but got all messy and had to call for help. If you put enough miles on bad roads or non groomed trails you may eventually get a big enough cut that is un-fixable no matter what is inside of your tires. Orange seal will seal pretty much seal everything else.

seems to dry out pretty fast. there than that.. seems to work

Used this my first time setting up tubeless, and it was as easy as could be. Flows well, sealed quickly. I found it easiest to use a bottle of water to flush the remnants out of the tube for storage (dont want to put it down the drain). The only improvement I can think of is that it would be nice if there were ounce markings on the bottle to get a more accurate idea of how much you put in.

I wanted this small 4oz bottle of OS Endurance for long bike trips. I think Orange Seal is the best however the bottle I received was marked with an expiration date of 07/22/2022. How important is the expiration date? What is the shelf life on this product? Would have been five stars if not for the expired date.

I own a small bike shop in the Adirondacks. Everyone up here runs tubeless, even the roadies. So over the past 10 years I have tried all the sealants. Ive tried making my own, used motorcycle sealant, etc. The best, by far, is Orange. It is EASY TO CLEAN UP and remove from tire treads and sidewalls, seals great and lasts quite long. Its expensive, but its really worth it to us. Id rather set up a wheelset with Orange once, then have to take the wheelset back in and redo the sealant because it didnt seal properly. That costs me money. So in the end the higher price point is actually saving me cash. The endurance I find is good for MTB tires and fat bikes, but the race version works best for road and gravel tires. The endurance is too thick for the smaller tires.

I like the texture of this stuff, as it creates a kind of latex layer around the inside. That can help the sealant do its thing. On the down side, I live in a hot and humid climate. I find that I need to check on the condition of the sealant every three weeks. It can separate and dry up in a summer month.

Love this product, I’ve used it for years. Made this purchase of the smaller bottle specifically to get the included injector. Arrived without injector. Returning it.
