    Works great. Just installed my first tubeless tires. No leaks and they hold air. EDIT: A couple of months down the road, had my first experience with a cut in a tubeless tire. On an urban ride with my gravel bike and felt the tire getting spongy. Started to get worried when I added air but the tire continued to leak (could hear the leak). But, in about a minute or less, the sealant sealed the leak and I was able to continue the ride. I have since ridden a very rough 55 mile gravel ride and the tire is still holding air. Great stuff. 2nd Edit: That tire with the cut... I was able to ride it until the tire wore out. The sealed area was never an issue through several thousand additional miles. Talk about being confident. Note: I just add a bit every couple of months rather than clean and refill since I will wear a rear tire out in one season.

    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.

    I ride about 6k miles annually. I’ve been using tubeless tires since about 2000, back when tubeless tires didn’t really exist, and all there was for sealant was Stan’s. Orange seal is my favorite lately. With good tubeless tape (I love muc off) and if you replace it about every 6 months, you’ll be done with flats unless you regularly smack rocks with your rims.

    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.

    This 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.

    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 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 used Stans, prior to finding Orange Seal, and now I use Orange Seal exclusively. Ive confidently ridden Utah running Orange Seal and have also ridden—and walked—Colorado on a rental wishing I had Orange Seal (and not Stans). No puncture is the same, but Ive ridden back to the trailhead after simple punctures (you barely notice until after the ride), and even torn knobs (more noticeable, like spew-sealant-noticeable—employed a plug along with OS sealant). I even rode out a bent rim after rubbing dirt into the void with OS drying shut in the gap (see picture), though had to keep pumping intermittently because the rim was out of shape. For normal punctures, OS is quick and effective. What I like BEST about Orange Seal is the bond at the bead which is so solid, it makes re-inflation simple; I find that invaluable on the trail. I dont get that sort of confidence with Stans. TIPS: For new rubber, add a bit more than the recommendation. It forms a film over the entirety/interior of the new tire. That said, the key to tubeless sealant is actually having enough sealant IN the tire for a puncture. Shake well and add via an open tire or stem. (They make a tube injector that works great.) Shaking is also key because Orange Seal does have solids that work in conjunction with the liquid.

    Had this screw go all the way into my tire. Thought it was hopeless but after adding air a couple times it actually was able to seal and could ride just fine

    This stuff is the best. And, when it dries, it dries weightless and peels out like snakeskin. Super easy to clean up. Since it dries weightless, and hold the seals up perfectly, I top off my tires with 2oz each season and dont have to worry about anything until I need new tires. Use with DT Swiss or Mac-Off Rim Tape.
