Orange Seal Cycling Tubeless Tire Sealant Refill, 8 oz

I liked the fact that it sealed up a puncture and I did not have to walk home!

I started using Orange Seal this year after starting with Stan's years ago and moving to a few years of my own Homebrew sealant. Here in the desert, Stans would dry out in about 45 days and need reapplication, and my brew lasted only a little longer. Orange Seal lasts at least 90 days (the longest I have dared to go) and could last longer in the heat. I just remarked to a friend who also uses Orange Seal, that I have not had one flat or need to use tire plugs since I mounted my current tires (one is tubeless ready, the other not). That is 900 miles of thorny, rocky desert in 7 months! He experienced the exact same thing. I also noticed no tire burps, it seems to glue the tire to the bead. Only complaint, is that it will gum up the presta valve cores in about 2-3 months making tire inflation (I raise or lower psi based on terrain often) tough. The solution is buy a 10 pack of valves from Tubo on Amazon for like $10. Its worth it and not a deal breaker at all. So far Orange Seal gets two thumbs up followed by a round of applause.

So far, I've been very happy with this stuff. In the past, I've used Stans and I've had small punctures where the stans was just spit out of the puncture and the tire went flat. I also had to keep inflating the tires if I went more than 2 wks between rides. Also, stans kept drying up and turning into a ball. So I decided to try this product... Now... Product stays liquid in the tire, no more dried up stans balls. I immediately started seeing many little bubbles on the tire from the new sealant filling holes (why didn't the stans fill these?) I no longer have to re-inflate tires between rides (still have to re-inflate if I have months between rides). No real cons. The product is a little more expensive than Stans and it doesn't go very far for larger mountain bike tires (running schwalbe 2.35" 27.5 tires). However its better than having your ride ruined due to a flat.

I like the 8oz. I have 27.5 tires, 3.0 on the front, 2.6 on the back. With this size I can top up my sealant every 8 weeks or so, I just use most of the bottle, 4oz in the front, 3 in the back. No point in storing the stuff for later use in my opinion, once its open it starts to clot. There is no injector, clean and use your old one. I did try the endurance stuff, but didn't like it as much as the regular stuff. It gummed up in my valve stem and had to be drilled out. Maybe I used it wrong. By the way, as a sealant it works very well here in the thorny Arizona desert.

This stuff works great - way better than the "brand popular" Stan's, and I only say this based on seeing my friends who use Stan's having both good and bad experiences. The price is a little higher than other brands, but in my opinion it's well worth it. Even clean-up is easy; OrangeSeal does not turn into a mess of spiderwebs inside the tire carcass when it dries up. I recently changed tires and the old tires had a thin, almost saran-wrap like layer of the sealant coating the inside of the tire. No stringy mess, no giant globs - just a smooth layer of sealant. I've been using OrangeSeal for the last 3 years... and I haven't had a flat for (yup) the last 3 years of riding fire roads, trails, and even downhill. Easily a 5-star product in my book!
