Orange Seal - Regular Formula Tubeless Bike Tire Sealant | Fast Sealing, up to 1/4" Puncture | for MTB, Road, CX and Gravel Bicycle Tires

Had to redo two tubeless tires on my gravel bike. Previously had issues with air leaks in between rides. This seems to have fixed all of that. No air loss while the bike sits. I have not had any chance to test puncture air loss ability yet but very happy so far.

This sealant has probably saved my ride a hundred times over the last few years. My area has a lot of thorns that go right through most tires. Years ago I used Gatorskin tires for training and GP5000 (with tubes) for racing, but I switched to tubeless and now run GP5000 S TR tires all the time and have less flats thanks to Orange Seal Regular. I've also used it in my mountain bike and gravel tires. Occasionally have to use a plug for larger punctures, but it always Seals and lasts for the remaining life of the tire. I've also tried a few other sealant brands, and found that Orange Seal is easier to clean off the bike than others. I like being able to inject the sealant directly through the valve stem, which is great for topping up every month.

Works for me.

This stuff really seals well. I was stupid and rode a sharp curb on my mtb. Not being used to xc style trail tires and there relative weakness, i lifted up the front but not the back and got a nasty snake bite with two holes at the tread and the bead. After the sealant spilled out a little it sealed it up, and now it still perfectly holds air. This stuff is fantastic. Oh and a year ago i got a nail in my gravel tire and it still holds air to this day.

Love Orange seal! I use this on all my bikes including; MTb, Adventure, and Road bikes. Have only ever had one slice (approx. 3/8”) and it sealed enough to get me the last 20 miles or so to camp.

I prefer it to Stans for road use. It does a better job of sealing small holes under higher road pressure (72 and 80psi on 700c 28")However It does dry more quickly. I top it up every month or two. To remove dried up gunk from inner tire use altas grey palm mechanics gloves and rub. Most everything will come in a big peelable glop. Older very stuff can be rubbed off using a palm sized rectangular natural rubber eraser used for cleaning machine belts.

Good product that seals quick and provides durable protection against leaks. Easy to add with included valve tube. Needs topping off with some regularity so not sure that is normal as this is the only sealant product I have ever used.

UPDATE: It's been over four months, and I have had zero problems, despite continuing to commute daily on the same route that was destroying my tires. In that time I have added air to my tires exactly once. Haven't needed to add any more of this product, still working great. I could not be more thrilled with how well this is working.Original review:I've never used a product like this before, and I haven't compared it with other comparable products. What I can say is, wow, this stuff really made a huge difference in my life. A month or so ago, my office moved and I started biking to work. Every day I would get a flat tire, or two, or more -- like the day I walked my bike the last bit in to work with a flat rear tire, changed the tube in the parking lot, reinflated it before going home, got a flat front tire going home, and saw the rear tire go flat again later that evening. I was tearing my hair out trying to figure out what was going on. Maybe the tubes I'm buying are no good? Maybe there's a lot of glass or other sharp debris on the route I'm taking? Maybe I'm not changing the tire correctly? Could my tires be underinflated or overinflated? Am I getting the wrong kind of tube? Is there something sharp stuck in the tire? Long story short, now I don't have to care about the answers to any of those questions because after pumping an ounce or two of this stuff into two fresh tubes, I've had zero problems. In fact, last Friday I was riding home and noticed a weird sound that turned out to be made by a chunk of glass embedded in my front tire. I pulled it off and immediately heard the sound of air escaping. So I ignored it and kept going, and after a few seconds the air sound trailed off and stopped. Got home and checked the pressure and it was 100% fine, and continues to be fine. I haven't changed a tube at all since buying this stuff and using it once, and both tires are holding pressure very well. My bike is my main means of transportation to and from work, and it's also just about the only exercise I get, so it's really been a lifesaver for me. Plus I learned that Schrader valves have cores, and how to remove and replace one, I had no idea, I ended up using some largeish tweezers to unscrew the core and it worked great, much less intimidating than I thought, 100x easier than changing a tube even once let alone multiple times a day.
