Fresh Gravel: Orange Seal Sealant
With the proliferation of tubeless tires suitable for gravel bikes, the need for sealant has increased. Traditionally, a single company has dominated this area of the marketplace, but we have been checking out several alternatives here at RidingGravel.com. You can check out our last review on sealants here. This time we are looking at Orange Seal, a sealant that has been around for a few years now, but has gained a solid following in the mountain biking scene.
What It Is: Orange Seal is for use in all tubes, tubeless systems, and for tubular tires as well. It has tested out in rims safely, showing no tendencies to corrode aluminum, according to the company. Orange Seal claims a 2-3 times longer lifespan in your tires than typical sealants and that Orange Seal will seal up bead seats better than the competition. Orange Seal has “Nanites” which they claim are particles suspended in the sealant which help seal punctures up to 1/4″ in size faster. The latex based sealant is claimed to be “eco-friendly” and Orange Seal also claims a wide temperature range for effective use. Orange Seal also makes a lubricant and a cleaner which you can find on their website here.
Look for a “Quick Review” on Orange Seal in about three weeks when we’ll have three months on a set of wheels infused with this orangey goo. We will also be setting up a few tires with the sealant to see how it aids, or not, in initial tubeless inflation. The final verdict will also include some experiences I have had with Orange Seal in the past, so stay tuned for that post which should go up in the beginning of September after the test period is over.
Note: Orange Seal sent over the sealant product for test/review at no charge to RidingGravel.com and we are not being paid, nor bribed for this review. We will strive to give our honest thoughts and opinions throughout.
I have yet to find anything good about Orange Seal. I have tried it in my mountain bikes and gravel bikes, all with different brands and types of tires and rim types (UST and Stan’s Type) and could never really get it to seal or close pores on tires.
It will be interesting to read your thoughts and reviews.
I have used nothing but Orange Seal and it works. My tires seal and hold air. On a gravel ride in April of this year I heard a loud repetetive banging coming from my front wheel. I had a small piece of plaster lathe board with a 1″ trim nail stuck right in the middle of my front tire making all the noise as I was rolling forward. I stopped and pulled out the nail and I immediately saw a small dot of white follow the exiting nail and that was it. That was in April, as I said, and I am still riding on this tire and have not dismounted it. I rode Ragbrai this year on it as well. Still holding air even though on Ragbrai I was running 70 psi in both tires ( I later learned this was not recommended for tubeless but it worked for a week lol). So yes I am an Orange Seal fan and would never ever put that corroding Stans sealant in any of my wheels.
I like your original recipe!
I have had nothing but success using Orange seal on my 29er. This sealed a tire that Stans couldn’t do, It also doesn’t seem to clump up over time like Stans does either. I will be using Orange seal shortly on my Cross bike too!
Maisie’s this year sold me on it. Never actually flatted, felt like maybe my back tire pressure had dropped ever so slightly. At the finish I picked at the “dirt” that had accumulated on my seat tube & it came off in a solid thin piece. It sealed up whatever happened back there so quickly the pressure barely dropped, I never heard the leak, and stayed sealed over a long day on nasty “roads”.
I haven’t gone tubeless yet because I don’t want to/can’t buy new wheels. I squirted some in my inner tubes a couple weeks before the Dirty Kanza. Not a single flat, despite bottoming out on a more than one cattleguard. Have barely touched the tires since then. When I topped off my tire pressure right before Gravel Worlds, I’d only lost about 5 psi. No flats at Gravel Worlds either.
Now that I’ve said that I’ll probably get 800 flats but it’s a little low-risk insurance if you’re running tubes, at any rate.
