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

I wanted this small 4oz bottle of OS Endurance for long bike trips. I think Orange Seal is the best however the bottle I received was marked with an expiration date of 07/22/2022. How important is the expiration date? What is the shelf life on this product? Would have been five stars if not for the expired date.

I own a small bike shop in the Adirondacks. Everyone up here runs tubeless, even the roadies. So over the past 10 years I have tried all the sealants. Ive tried making my own, used motorcycle sealant, etc. The best, by far, is Orange. It is EASY TO CLEAN UP and remove from tire treads and sidewalls, seals great and lasts quite long. Its expensive, but its really worth it to us. Id rather set up a wheelset with Orange once, then have to take the wheelset back in and redo the sealant because it didnt seal properly. That costs me money. So in the end the higher price point is actually saving me cash. The endurance I find is good for MTB tires and fat bikes, but the race version works best for road and gravel tires. The endurance is too thick for the smaller tires.

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!

The best sealant out there for hotter areas and fine enough to seal sidewalls unlike Stans which seep. Doesn’t dry out as quickly. If you ride in colder weather, you might be better off with the standard formula.

Had this screw go all the way into my tire. Thought it was hopeless but after adding air a couple times it actually was able to seal and could ride just fine

I switched from Stans to Orange Seal last season and I have been super happy with the change. Stans was making my tires really sticky on the inside, the sidewalls were sticking together really bad making it tough to add sealant (I normally pop a section of the bead off rather then inserting through the valve). I couldnt be happier with the Orange Seal. I pulled 5 goatheads out of my tire the other day. When I pulled the goatheads a little air escaped, I put my finger over the hole for a second and let it do its magic. Still running those tires, no leakage. You can see some wet spots where it seals, but honestly I dont know what we did before tubeless. With how many goatheads and cactus spines I hit in a season, I would be constantly changing tubes.

I’ve always used Stan’s because it came with my bike and I’ve never put much thought into it. Switching from Stan’s to this I can actually feel a difference in the way my bike rides and the seal seems more durable. Been using orange seal for 6 months now and I won’t go back

Did not contain the filler attachment as shown in the pictures

seems to dry out pretty fast. there than that.. seems to work

Use this in my MTB, gravel, and road bikes. Was out for a road ride recently and suffered a puncture that I never knew about until I got home and saw some sealant had sprayed onto bike while it was sealing up. Same tire a couple days later, hit a junk of metal in the road. Spewed sealant for a bit as it did its magic but only lost 10-15 psi and was able to continue my ride. Outstanding product from a great brand. Highly recommend.
