> 3 dayUse 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.

> 3 dayI 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.

> 3 dayIve 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.

> 3 dayYou 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.

13-04-2025Orange seal is great stuff. Bought this one as it came with injector per the description, it was not included however. Seller needs to correct listing.

> 3 dayafter a few years of stans I decided to try Orange seal. Stans seems to not preform super well if you need to reinflate a tire with C02. Ive heard orange seal is a bit more robust with its temperature responce. the C02 apparently encourages Stans to freeze/ coagulate on its own in the tire as opposed to hitting the holes and sealing. 4 rides in so far so good. update as experience dictates

Greater than one weekI own a small bike shop in the Adirondacks. Everyone up here runs tubeless, even the roadies. So over the past 10 years I have tried all the sealants. Ive tried making my own, used motorcycle sealant, etc. The best, by far, is Orange. It is EASY TO CLEAN UP and remove from tire treads and sidewalls, seals great and lasts quite long. Its expensive, but its really worth it to us. Id rather set up a wheelset with Orange once, then have to take the wheelset back in and redo the sealant because it didnt seal properly. That costs me money. So in the end the higher price point is actually saving me cash. The endurance I find is good for MTB tires and fat bikes, but the race version works best for road and gravel tires. The endurance is too thick for the smaller tires.

> 3 dayI 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.

13-04-2025Sealed the multiple pin hole leaks in the side walls of my Vittoria 29er tires. Stan just wouldnt do the trick.
