> 3 dayTubeless is a game-changer and Endurance Orange Seal sealant is an easy, dependable choice. Top off or check every three-ish months and you’re good to go! I’ve been running on my 38c all-road bike and haven’t needed to use a dynaplug or spare tube in over 18 months of riding.

> 3 dayThis product is flawless. It works like charm, i ran over a cactus going down hill and tires held and sealed right back up. This sealant also works for a long time so ur not buying a new one over and over. This sealant only down side is if you don’t ride often like 1-2 a month it drys up and doesn’t give you the protection I usually would.

> 3 dayI 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.

09-06-2025Its 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 Tubes are outdated old school tech that has suffered the same fate as rim brakes and steel frames.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.

Greater than one weekI have been using Stanz for quite some time and it seems like I have to replace more of it than is actually being used to seal leaks. For some reason a very small hole will leak out Stanz for quite a long time until the hole is sealed however, my most recent whole would never seal. My brother is an avid mountain bike rider and road cyclist and told me to try orange seal out because that is his go to sealant and that he swapped over from stanz years ago so I took him up on it. Im using a 6fattie and put 4 ounces of orange seal in it, rotated the tires eight or 10 times filled it up and he has never leaked since. I saw a small amount of the sealant exit the hole that was causing me grief but that was it hole was sealed. I did not remove the tire from the rim and clean everything out, I just took recommendations from various websites and forums and they said just put it in and it will do its magic. I have nothing bad to say about it.

> 3 dayIve 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.

> 3 dayI 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.

> 3 dayDescription says syringe comes with bottle of sealant, it does not. I contacted seller and nothing came of it. Be aware when purchasing.

Greater than one weekI 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.
