Orange Seal CyclingEndurance 16oz Sealant Refill(Return to Product Page)

I've tested this OS Endurance formula for 3 seasons. It seems to work better than anyhing else out there. I haven't tested it in sub-freezing temps yet. It stays effectively liquid for almost a year. I can put another 1/2 dose in the tire when I'm in doubt. No problems with maintaining pressure or sealling of punctures. Thumbs up!!!

When ever I get a flat in my sewup tires. I put in a small bottle of Orange Seal and 95% of the time it will be sealed. Have gotten many more miles out of those tires.

Sauce does its job. Never flatted, never noticed punctures over an entire cx season and many offroad training rides

Last 3 to 4 months

Good sealant. - Never that easy to use!

As lifelong fan of tubulars, the puncture used to mean replacing the tire. Now I can wear a tire out before replacing. Also no roadside struggling to change them. What a money saver!

Road Tubeless over 17K miles actually better than advertised

I have been using in all my tires Great sealant

Rode 20 miles with a 58 inch screw in the tire and this stuff kept enough air in tire to make it home. Works great for 5 month then slowly loses it's leak stopping power. I use the removable valve stems to put it in the tire, this brand does not plug the valve stem and flows in with just squeezing the already beaded tire. I have used this brand for 3 years and have used probably 4 quarts during this time for MTB, gravel, and road.

Very happy with this. I can refill smaller travel sized bottles and many many tires. Lots of particles to seal Larger punctures. Doesn't dry too fast and easy to clean if it spills.

Orange seal seems to work better and last longer than other sealant products.

Orange Seal is always sealing up thorn holes in my tubeless tires. I decided to add 60ML to my tubes on my backup bike. On a recent group ride, we encountered thumb tacks in the road. (Dirty Trick). I picked up 3 in my back tire and 1 in my front. I rode all the way home about 10 miles on hard tires. Since they were Continentals and hard to work with my arthritic hands, I took the wheels to the bike shop. They were astonished to discover that the Orange Seal had essentially turned my tubulars into tubeless tires. I was in there the other day and a MTB customer was starting to buy another brand of sealant. They suggested he try Orange Seal because it does not corrode the spokes like the other brand.

I have used Orange Seal for two years now on both my 29er gravel bike with 2.3 tires, on my winter commuter with 40c gravel tires, and on my road bike with 32c gravel tires. After a winter of commuting, my tires had dozens of little spots on them where the sealant had filled up some small holes. The sealant seems to work best at lower pressure, say around 25 to 40 pounds, so I never noticed any of the incidents on the gravel tire, or on my 29er. On the road bike, at higher pressure, when a puncture occurs, there is a hissing sound as pressure escapes from the tire, and sealant may spray a bit depending on how high the pressure is. But the leaking stops as the pressure gets a bit lower. Not sure how large of a hole it will seal, but it definitely works great for the typical winter debris of glass and sharp rocks.

I had used stans sealant for a number of years and felt like it was the best out there. Then saw a review on the Internet that suggested orange sealant might be better. After using it in eight tires both new and old , I am convinced it is the best stuff out there. In addition a friend has given me some tips to get those stubborn to seat tires on. Taking the valve core out of the valve stem helps allow a higher volume of air to enter the tire helping the bead get pushed in and seat. Also putting a thin layer of soapy water on the bead to help at seat has worked also. And last using the orange sealant. Hope this review helps. Would strongly recommend giving orange sealant a try.

Orange Seal Cycling Endurance 16oz Sealant Refill is a great product. This is the smallest size refill bottle to buy if you only have a couple of bikes. This product works great as long as it is used as recommended by the mfr. I use it with road bikes. I use 2 oz when I change the tire and refill with 1 oz before 3 months and I'm covered from simple punctures. I carry arrow plugs in case I get a big puncture and this sealant still works well enough to ride home.

I converted my smart trainer bike to tubeless w this. The first attempt was a mess, but a bike mechanic set me straight. Then I ordered 1/2 ton of pavers. My hand truck was had its tires detached from its rims for 20 years. I applied this and they've held 30 psi for weeks. I hauled the pavers to the backyard, and 300 lbs of extras back down to the drive. This works very well.

Endurance still dries out. I can't tell if it's really happening any slower or not.

I have used Orange Seal exclusively for many years after a recommendation from my LBS. Use for road, mountain and gravel tubeless setups, find it's easy to work with for initial and remounts, easily cleans up with soap and water. I am in the desert southwest, very dry conditions and I do think the Endurance performs a little better over the standard especially in not drying up prematurely. Has very good performance in sealing the bothersome cactus thorns and radial tire cord annoyances that are common for us. I ride a lot of miles on tubeless tires setup on Orange Seal and have not had an issue, recommend often.

I've used this on tubeless [obviously] and tube type tires with excellent results. Since putting it in my tubed tires, small punctures do not have any effect and are sealed without even noticing. I highly recommend this for everyone.

I have used Orange Seal for the last few years. I have found it to last longer in the heat here in Arizona. I switched from Stans regular which also works well. I have been able to plug some large snake bites and ride home. I never notice smaller punctures from thorns and such as they seal immediately. I have found that you do need to ride a few low impact miles to allow for full coverage. Orange Seal is a great product!
