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

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.

Ive had this injected for close to a month now, and so far its worked perfectly. I initially put the same amount of sealant on both my Minions, but it seemed that my rear tire was leaking a tiny bit of air over the course of 4 days (ridden once), so I ended up putting in an additional 1.25 oz, which seems to have done the trick. Using this Along with the KOM sealant injector worked really well on the tubeless stems I purchased. Had no issues with clunks getting stuck in. Some people complain about a smell in other agents. Didnt notice anything with this, but I didnt go out of my way to smell it either. I havent noticed any punctures yet (hopefully I can just avoid those altogether) but Ill update my review in the future for anything I notice.

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.

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.

I 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.

My first attempt didnt work as I did not have the tube from the sealant cover the stem. The second time, I was able to firmly secure the sealant tube over the stem and squeeze the sealant into the bike tube. I road the bike twice since the repair and can say it sealed the leak quite well. I no longer worry about minor leaks when riding.

This is a really good sealant. In several thousand miles using this sealant, I have not been stranded roadside fiddling w tubes. It seals much better and holds longer than Stans. If you use Orange Seal (or other) threaded stems, you can add sealant without even unmounting the tire. A reliable tubeless tire setup with Orange Seal is the safest way to ride. No blowouts or pinch flats that might cause a crash or getting stuck hazardous places messing w tires when conditions are unfavorable. Orange Seal will keep you riding rather than messing with tires. I didnt comment about use, because its incredibly simple to pour or inject then inflate (often with only a track pump needed. Put a few OZs in, pump, spin, ride. Refresh every few months.

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.

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.

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