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

Great product and amazing service!!!

this stuff works great and smells good

I had two flat tires on my mountain bike, so I tried this before I was going to replace them and it worked perfectly. They both had slow leaks, and as soon as I would fill them up with their like an hour later, they would be deflated and after using this stuff, it’s been almost a week and the tires are still filled!

I found out about Orange Seal after much, much aggravation with Stan's. When I used Stan's, my tires bled constantly from the sidewall. Specialized told me "we recommend not using Stan's 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 (I'm 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 Stan's 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. Stan's 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 that's 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! I've been sold on Orange Seal ever since. I'll never use Stan's again. It costs a couple bucks more which I didn't 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.

One of the best two sealants on the market along with Silca’s.

Low pressures in MTB bikes mean you can use the thinner sealants. But if your riding gravel or road bikes you need something that seals at higher tire pressures. A thin sealant is designed to work at 20 psi or less. It just sprays out of my gravel tires at 35-40 psi. So, I tried Orange and it works very well. I use the regular formula to setting up new tires with those seeping sidewalls. Then, I use the endurance formula for refills. It also seems to last much longer than the regular formula. Of course that sidewall seeping is really about how supple your tires are. Anyway, I use different sealants and always use Orange in gravel/road tires.

This sealant was easy to inject into my tubeless tires, no mess. On my first ride, I got a small 1mm that apparently went unnoticed. Didn't realize it until I got home, put it on the stand to perform routine maintenance/inspection. Saw what I thought was a feather sticking to my front tire. Tried removing it until I saw it coming out of my tire. Upon further inspection, it was excess sealant compound that did it's job in sealing the small puncture. Air loss was very minimal if at all. This stuff works!!!

I'm always leary when I order "only 1 left", not knowing if I'm going to receive a quality item, or a "this is what we had left" not quite all there item. The Orange Seal came as described, and I expect to continue having no-flat rides.
