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

I’ve tried a number of tire sealants, and I find Orange Seal to be the most reliable. It works on holes and leaks, it’s easy to refresh by adding it through the valve stem, and it’s reasonably priced. It’s a solid bet for a sealant.

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.

I was a first time user of tubeless tires so I didn’t know much about them. I got an 8 ounce bottle of this stuff and didn’t get my first flat for well over a year and only because the original application had dried out. So I ordered a quart this time and topped off the tires. They’re still rolling and still holding air. Everybody says your tubeless tires will loose a few psi per day but I check mine any every two weeks and only have to add about 4-5 psi. Could be the tire or it could be the sealant idk but this stuff inside gravel king ss+ tires works great.

Before I had tubeless rims, I used this in my inner tubes. Didn't completely prevent flats, but there are times I made it home instead of having to walk because of this stuff. For my tubeless tires, it works great. I tried some other that I got as swag at an event and it didn't seem to seal as well. Going on 3 years, no flats.

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.

Not only high quality sealant to quickly stop leaks but also has a great little kit with the tools you need to fill up your tire with sealant without spilling any. The kit will fit in most any bag - or your Camelback - without any trouble. I never have flats anymore since using Orange Sealant.

Have now used this on 4 tubeless conversions (8 tires total) as well as a quick fix for slow leaks that I have encountered while out in the wilds (see pic). Has worked every time for both initial set ups and top ups. Pro tip for initial set ups, be sure to lie the tire down flat overnight to seal the bead, pump up, and flip it over in the morning on the other side, before mounting on your bike. Just purchased a second bottle for my shop use.
