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

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.

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 have been using Orange Seal in my mountain bike tires for years based on a recommendation from my LBS and recently started using it on my road bike after going tubeless. It does a really nice job of sealing leaks as expected and cleans up nicely after a blowout. Non-corrosive on alloy wheels and priced competitively with other sealants on the market as well. I add the recommended amount sealant every 3 or 4 months. Good Stuff!

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 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.

I hate fixing flats on the side of the road so I'm continually looking for the best solution to prevent that from happening. Orange Seal is the easiest answer that I have found. Costs more but it's worth it to me.

It works as advertised. I use Orange Seal sealant in my Easton gravel wheelset running Maxxis 700x40mm Re-fuse tires. Initial set-up has 2 oz. per wheel and I've been issue free despite some noticeable punctures which quickly sealed. I air my tires before each ride and do notice a drop over time but it's not an issue for me. When installing, I put all but 10% of the tire on the bead then rotated the uninstalled part of the tire to the bottom or at the 6 o'clock position when holding it vertical. Save yourself some money and take a pass on the syringe and tubing gadgets and buy the 16 oz. bottle (use the remaining to fill your buddy's tires!). Pair it with a measuring cup then pour into the tire and rotate the uninstalled part to 12 o'clock and finish tire installation. Use a pump or air compressor to finish seating the bead then spin to ensure the sealant distributes evenly. You'll notice some temporary orange drips as the sealant fills the pores in the tire sidewalls. Wipe clean and enjoy!

Haven't flatted yet but airing up the tire sealed quickly.

I always use this sealant, I love their products

I was riding mountain bike trails in southern Illinois when I punctured the rear tire on my gravel bike. I couldn't see the puncture but after the third day on the trails the tire would only hold air for about an hour. I converted to tubeless. The tire sealed up and I rode for a few more days. I'm now convinced that tubeless is the way to go if you are riding anywhere that punctures are likely.

Excellent as used on the label. I have used Orange seal for years and have never been stranded.

great competitive price, too early to review its ability only a few rides with it installed.

I prefer the endurance formula for both road and MTB use as it seems to last longer than Stans while still sealing as well.

Been using these since i went tubeless. No complaints

All I've used since switching from SNT.

My use consists of 38-42mm allroad underbiking.

Easy fill on my commuter tires.

1000 miles so far and no flats

I have tried a few different brands and this has worked da best by far. This sealant has worked on every puncture I have had.

Using on tubeless gravel tires and tubeless rims. Works great!

Been using this for a year in my gravel bike. Sealed the tires well. Seems to hold up well, requiring top-off maybe twice per year.
