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

Was looking to go tubeless, Picked up some of this because it was recommended . And so far Im liking it .

I’ve always used Stan’s because it came with my bike and I’ve never put much thought into it. Switching from Stan’s to this I can actually feel a difference in the way my bike rides and the seal seems more durable. Been using orange seal for 6 months now and I won’t go back

Finally got around to replacing my mtb tires. This fluid didnt seem much thinner than Stans when filling the tire. Manufacturer says 4oz, my tire/wheel took 12oz plus. It is still seeping out the spoke nuts. Most irritating, every time I press the valve stem I get sprayed with fluid - regardless of valve stem location or how long the wheel has been stationary. Havent ridden enough to determine how long lasting it is. Doubt Ill buy it again.

This is a great product, however the picture they use shows a tube for easy filling and it certainly does not include this with the bottle.

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.

As for the product, unless youre actually racing where money/prizes/pride is at stake, this is your choice for MTB tubeless sealants. Ive meticulously tested this against Stans and generated a list of pros and cons. While similar overall, the Orange Seal Endurance does edge out the Stans. Both are good sealant choices, but the OSE is better. My main issue with the 32 oz mechanics bottle specifically is, when the item ships, its common to see the seal under the cap broke contributing to leaks. Ive ordered a case in the past and it arrived in a way where it looks like one of the bottles bursted. Orange Seal has to do a better job at using a better seal to resist leaking during shipping and handling.

I’ve used orange seal for years. It has been dependable and consistent. It works well for keeping my tires inflated and rolling. It is water based so easy to use and clean up.

quick delivery and product has good reputation

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.

Use in all my bike tires
