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

Ive had good luck using this product over the past few years. Ive just had normal pinholes in tires and this has sealed them very well. However the main reason that I like this product is that it lasts longer than Stans! Whenever I use stans, I have to refresh it every few months because it would dry out and turn into a little rubber ball inside my tire. I would have to break the bead and pull it out at least once a year. I dont have this issue with orange sealant. It stays liquid even a year later. My tires are also holding pressure very well between rides.

Received item in good condition, took awhile to get here but that was expected.

I am using this in a 29” WTB TCS tire and it seals very well. I used Stan’s for a number of years and always had a significant amount of air loss over time. Orange seal maintains the air in the tire much better.

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

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.

Use in all my bike tires

I ended up having Stans in my front tires on both my road bike and MTB, and Orange Seal in the rear tires. (Dont ask, long story...) Ive always read that you should never mix the 2 products. Being a skeptic, I decided to test that claim. I had a little bit of Stans left in a pint bottle, about 0.5 oz. I poured it into a small glass jar, then added 0.5 oz of Orange Seal to it. I gave it some mild agitation by shaking, basically to simulate the mixing youd get as you ride. The 50/50 mix blended perfectly - no emulsion, separation, settling - just a perfectly miscible blend of the 2 fluids. Id have no problem feeling comfortable to use that resulting 1 oz next time I top off a tire.

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.

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.

Should be enough if you have multiple bikes. If you have just one bike, this should last all year long. Good value. Wish it would have came with the filler tube, so of you do have one you may want to get one to make adding sealant to your tire easier. I do find the Orange sealant tends to dry up quicker than other brands, but from my experience it seals better when you get a puncture. With the large bottle you can top off every 2-3 months.
