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

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.

This stuff has been so reliable over the years. Ive tried Stans, DT Swill, Continental, even Peatys - yet I havent used anything as good as Orangeseal. Yes - the price is a little higher than other brands, but in my opinion its well worth it because it lasts longer before drying up/evaporating, and it seems to keep punctures away. At times when my friends are refilling their Stans sealant, my tires still have a good amount in them. In other words, cheaper doesnt mean better! Clean-up is easy; OrangeSeal does not turn into a mess of spiderwebs inside the tire carcass when it dries up. No stringy mess, no giant globs - just a smooth layer of sealant. Ive been using OrangeSeal for the last 3 years... and I still havent had a flat for (yup) the last 3 years of riding fire roads, trails, and even downhill. Easily a 5-star product in my book. Im only buying more because I want to top up during the hot summer were having locally.

Saved my butt out riding, took a 3 in nail and this surprisingly sealed that large hole

Did not contain the filler attachment as shown in the pictures

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

You will not find a better tire sealant. Orange Seal endurance lives up to its name. I live in Colorado and Goat Heads and massive constant construction mean flat tires every week unless you use Orange Seal Endurance in your tubeless 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.

Use this in my MTB, gravel, and road bikes. Was out for a road ride recently and suffered a puncture that I never knew about until I got home and saw some sealant had sprayed onto bike while it was sealing up. Same tire a couple days later, hit a junk of metal in the road. Spewed sealant for a bit as it did its magic but only lost 10-15 psi and was able to continue my ride. Outstanding product from a great brand. Highly recommend.

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.

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.
