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

This is a great sealant. Safed me from having a flat numerous times and last forever!

Easy to use and works great!

My preferred tire sealant. It’s economical and effective. I use it in all of my 2Bliss mountain and gravel bikes and it’s never let me down.

Product works great for sealing leaks. Have used it for several years

UPDATE: My tubeless rear tire on my YUME Y-10 does not leak anymore! AMAZING!! I am adding back an additional star inasmuch as the product actually worked! I wanted to love this product so much, but the supplied "injector" was indeed a significant letdown! I couldn't wait until the orange seal product arrived, knowing that the rear tubeless tire on my YUME electric scooter had a very slow leak, requiring an easy solution. I read the supplied instructions printed on the bottle label carefully and removed the valve stem as required to fill the tire with the "correct" amount of orange seal product. As I attempted to connect the supplied polyethylene hose over the top of the valve stem I discovered that the outside diameter of the valve stem was larger than the inside diameter of the supplied plastic pipe, a clear "NO FIT!" I had to borrow an adapter from an brake oil bleed kit to attach to the plastic piping to avoid spilling the product everywhere! Then, once I figured out how to put the product into the tire without issue, it also seemed odd to me that the product was supplied in a somewhat opaque container, without any ounce or milliliter indexes on the sides, and the chart indicating the "correct" amount of product to use omitted small wheel high speed scooter tires where the product is likely used often, ugggh. The good news is that as of 24 hours later, the tire seems to be holding the air! AWESOME. Thanks for reading my reviews, from R1, a former manufacturer's rep!

This sealant lasts a lot longer in the tire before it dries up. Not sure about it's actual sealant capabilities. I have yet to get a flat. But I have a little more confidence with this brand than the others I have tried. I can still hear it "sloshing" around in the tire after three months -- which is better than all the rest.

I was an idiot to assume they would do the bare minimum with the injector. I thought the bottle would have markings on it so you could know how much sealant you put in the tire. There isn't, so I guess they expect you to just go by feel, put too much in, and need to buy more because you're constantly wasting it. Don't pay an extra $3 for a 10¢ rubber tube.

My first attempt at refilling my tubeless tires. Bought this and a pressure valve tool. 5 min tops

Emergency repair

Good product

Use it on my new fat bike and it holds quite well even in the cold weather.
