Orange Seal - Endurance Formula Tubeless Bike Tire Sealant | Long Lasting, Fast Sealing | for MTB, Road, CX and Gravel Bicycle Tires

This stuff has been so reliable over the years. Ive tried Stans, DT Swill, Continental, even Peatys - yet I havent used anything as good as Orangeseal. Yes - the price is a little higher than other brands, but in my opinion its well worth it because it lasts longer before drying up/evaporating, and it seems to keep punctures away. At times when my friends are refilling their Stans sealant, my tires still have a good amount in them. In other words, cheaper doesnt mean better! Clean-up is easy; OrangeSeal does not turn into a mess of spiderwebs inside the tire carcass when it dries up. No stringy mess, no giant globs - just a smooth layer of sealant. Ive been using OrangeSeal for the last 3 years... and I still havent had a flat for (yup) the last 3 years of riding fire roads, trails, and even downhill. Easily a 5-star product in my book. Im only buying more because I want to top up during the hot summer were having locally.

I had Stans NoTube Race Sealant in my tires. That was a fresh conversion to tubeless. I have no prior experience. My son did it for me. It worked well at first, but then my tires started losing a lot of pressure after about a month. I added 3 oz Orange Seal Endurance to the leakiest tire, and 1 oz to the other. I also tightened the valve stem nuts, so I cant say the Orange Seal was the ticket, but I think so. Ive been riding for a few weeks since, and my tires are only losing about half a pound each time I check, and theyre probably losing that in the process of checking them, as I have to use a Schrader adapter with my current pump. I have 650B tires, and ride about 75 miles a week, mostly on pavement. I will continue with the Orange Seal Endurance, as it was very easy to use, and seems to work like a charm.

Works better than the white stuff, I get goatheads in my tires often, I just pull them out and keep riding, works like it’s supposed to!

I am using this in a 29” WTB TCS tire and it seals very well. I used Stan’s for a number of years and always had a significant amount of air loss over time. Orange seal maintains the air in the tire much better.

I first used Endurance in the AZ desert and it worked great for cactus punctures. It stays liquid longer than my previous brand so I’ve switched to using it exclusively.

Love this product, I’ve used it for years. Made this purchase of the smaller bottle specifically to get the included injector. Arrived without injector. Returning it.

This is a really good sealant. In several thousand miles using this sealant, I have not been stranded roadside fiddling w tubes. It seals much better and holds longer than Stans. If you use Orange Seal (or other) threaded stems, you can add sealant without even unmounting the tire. A reliable tubeless tire setup with Orange Seal is the safest way to ride. No blowouts or pinch flats that might cause a crash or getting stuck hazardous places messing w tires when conditions are unfavorable. Orange Seal will keep you riding rather than messing with tires. I didnt comment about use, because its incredibly simple to pour or inject then inflate (often with only a track pump needed. Put a few OZs in, pump, spin, ride. Refresh every few months.

Bike shop, and mountain-biking family members all extoll going tubeless. So far, so good. I did four tires in short order without adapter to valve stem. Highly recommend short You Tube videos to prepare/plan. Another set of hands would have been helpful servicing 29 rims/heavy tires with liquid sloshing around, still managed without spilling a drop.

Orange seal is great stuff. Bought this one as it came with injector per the description, it was not included however. Seller needs to correct listing.

Ive primarily used Orange seal on my bike. Not for any reason, I am new to the whole MTB scene... It was just one of the first better reviewed sealant Ive seen. My impressions of this bottle is VERY good. See, I bought brand new tires and immediately caught a hole in them. The stock sealant from the bike shop install wasnt able to cut it, the hole was too large for that. But I didnt feel like buying new tires are the time either so I patched the hole myself and bought new sealant ( this stuff ). The tubeless install went flawlessly. This sealant works. After a couple of weeks though I started losing air pressure. At the end of a ride my tire would eventually be really flat. I figured it was the patch work... patches are supposed to just be temporary after all. But just for the heck of it I topped off my sealant because I didnt hear any leaking. Just like that problem solved. A few more weeks and a couple more rides later and my tire still has the same amount of air in it as it did before. This stuff just works. Time will tell on if it can seal tire damage but in terms of a tubeless tire install and sealing, the sealant just works.
