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

Seals tires well, no Stanimals. Does dry out (endurance lasts longer than original) so I add a few ml every 4-6 weeks. Including a dipstick would be nice Orange Seal.

Orange 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.

I am a nail magnet. I on every ride get a flat. My life was miserable and I cursed those bicycle designers. Then came my new tubeless ready bicycle. I, a novice. Put a tape on the rim. Installed Valve. Added this Orange stuff and pumped. The tire I added this on already had well over 20 punctures. I fully expected it to spray orange goo all over the die. I just couldnt believe watery orange water with black fine powder in it can seal my punctures. Jesus Martinez.. 3 wooze a little bit of orange goo and it stopped. Pumped the bike to 50 psi and it held. Holy guacamole. I went through the bushes and riverbeds and pulled out dozen goathead. Air leaked when goathead was popped out but quick spin on the tire sealed it. Not even a whole turn, half turn and it stopped leaking air. After 3 months or so I am finding out that it may not be sealing it permanently. Tire continuously leaks air a bit. It loses 5 psi in a week of being idle.. maybe 5 psi a month.. it depends. So I check and pump at least every week or before I go out. But that is only maintenance it takes. I now have utter confidence that Orange will hold air. I made a 70 trip and I did not worry about a puncture. My bike is a gravel bike and I carelessly jump in to gravel trail whenever I see them. I dont believe I will have to carry my bike 11 miles again because it had a goathead. I am baptized and born again.

I first used Endurance in the AZ desert and it worked great for cactus punctures. It stays liquid longer than my previous brand so I’ve switched to using it exclusively.

I found out about Orange Seal after much, much aggravation with Stans. When I used Stans, my tires bled constantly from the sidewall. Specialized told me we recommend not using Stans as it has corrosive properties not compatible with our tires. Kenda - ate through the sidewalls. Then one day out on a brand new $60 tire, I got a cut about 1/4 long. Already really pissed at how much MTB tires cost, cutting a brand new one like that sent me into orbit. I took the tire apart, cleaned it extensively, put a patch on the inside of my tire where the cut was (Im running tubeless), let it dry. Tested the hold by hand before putting the tire back together on the bike. I really squeezed & pushed it, the patch seemed solid. Put Stans in, aired up the tire. Checked again - yep, holding air. Loaded up & drove off to hit the trail. Get on the trail and 15 minutes into my ride, the tire goes flat. Cussing like a sailor, I walked back to my truck, threw my stuff in & went back home. Took the tire apart, and the patch is laying in the tire not glued to it. Stans ate the glue off. Refusing to give in to tossing a $60 tire in the trash, I went to a couple bike shops explaining what had happened. One shop recommended Orange Seal, saying thats what they use in the shop. I once again, went through the process of patching the cut in my new tire. Put it all back together, checking the air constantly for any sign of loss. Went on my ride. It held! In fact, it held so well that I rode that tire until the tread was gone with the patch STILL holding! Ive been sold on Orange Seal ever since. Ill never use Stans again. It costs a couple bucks more which I didnt like, but it does work. I think both brands are about 200% profit to the manufacturer which is why I gave it only 3 stars on Value for Money, but if you have to pay, might as well pay for something that works.

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.

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.

Works better than the white stuff, I get goatheads in my tires often, I just pull them out and keep riding, works like it’s supposed to!

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

The best sealant out there for hotter areas and fine enough to seal sidewalls unlike Stans which seep. Doesn’t dry out as quickly. If you ride in colder weather, you might be better off with the standard formula.
