It’s easy to get stuck in a rut when it comes to tubeless tire sealant. Many of us experience cuts, punctures, slices, and other damaging events that can completely destroy a tire. But Orange Seal challenged us with a question – why keep going back if there’s an issue, if it’s not sealing? Orange Seal is unique in that it coats the inside of your tire entirely. When the company went to work on a better solution for tire sealant they had a few goals in mind: 1) They want to be able to seal holes in tire sidewalls. 2) They wanted to be able to address larger punctures and sidewall cuts. 3) They wanted it to last longer than what’s on the market. 4) They wanted it to be non-caustic. 5) Finally, they wanted it to form a permanent plug in the case of a puncture, so you can continue to run the tire for a long time.

Their formula works at high pressures, is non-corrosive, and was the result of 2.5 years of development effort. The typical 27.5/29” tire requires 3-4 ounces of fluid. Once you think the orange sealant might be dry, simply deflate the tire, remove the valve core, and insert the provided dipstick to see if there is or isn’t any wet sealant left inside. If there isn’t, simply add more – it’s as easy as that, no need to remove boogers etc. Orange Seal comes in three different models, the standard, which seals the fastest but also lasts the shortest amount of time, the endurance version, which seals slightly slower – say 2-3 revolutions – but lasts 60 to 180 days depending on your riding conditions and environment. Finally, there’s a sub-zero version which works in extremely cold conditions. 

The video and photos below show Orange Seal in action, and the results are pretty dang impressive:

    "why keep going back if there’s an issue, if it’s not sealing?" agreed, which is why I'm done with their product. Spent literally a week retaping a rim, adding sealant, & coming back to a flat tire an hour later. air was always escaping somewhere from the rim. finally dumped the orange seal, put in stans, boom done. their sealant seems to work fine for tire punctures, but if you've got a leak in your rim tape or valvestem, you're screwed. & I, for one, do not do a perfect job on that every time, & a tight fitting tire will often abrade the tape enough when it's going on to put make it leak slightly.

    Actually ran into a guy at the trailhead yesterday, got his bike off the rack, realized he had a flat front tire. messes with it, realized the air is coming through the valve hole. deflates the tire to pull it off, & what do I see? orange seal.

    Not doing a good tape job can cause too much sealant to get under the rim tape and deactivate the tape's adhesive. This can cause the tape to lift and will make a proper seal impossible. Probably the cause of your week long issue. Also, after you inflate the tire you should go for a quick ride around the block. Sealant will swash around, plugging every manageable leak.

    Like the article says, "Orange Seal is unique in that it coats the inside of your tire entirely." Got to swash it around to coat the tire, not just adding sealant and letting it sit for an hour.

    I've been running tubeless since 2002. I know exactly how to seal leaks like this (a better method than your ride around the block is to take the wheel in both hands, & "swish" it, then rotate the wheel an eighth turn & do it again, until you've rotated the wheel 360 degrees. then put the wheel on the bike & spin it several times in the next hour.)

    I know how to tape rims. best example I can come up with is when I finally switched out the orange seal for Stan's, I didn't retape it, & it sealed fine.

    It's the sealant. It works fine, until it doesn't, & until it happens to you, you never believe people that it's been a problem.
