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

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.

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.

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.

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.

This is a very foamy sealant that I could not inject with a syringe. Save the cap tube injector! Very effective at sealing new tires; especially seeping sidewalls. However, the foam sealant sets up quickly and I don't think its as effective at finding punctures FAST. Kinda messy but very very good at what it does. So ... I really like this sealant but will probably switch to the Orange endurance formula, which I think is a more fluid sealant and easier to work with.I also want to add that I use this sealant on road and gravel bikes only. For mtb bikes, I kinda prefer another brand sealant. This other brand sealant was designed for low pressure tires that need to seal punctures quickly ... mtb riding. On the road ... circumstances are different and I love Orange.

I use this for a gravel bike @ 30psi and have nothing but great things to say about it.

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.

great sealant. easy to clean and remains liquid for a very long time.
