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

Sealed the multiple pin hole leaks in the side walls of my Vittoria 29er tires. Stan just wouldnt do the trick.

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.

My first attempt didnt work as I did not have the tube from the sealant cover the stem. The second time, I was able to firmly secure the sealant tube over the stem and squeeze the sealant into the bike tube. I road the bike twice since the repair and can say it sealed the leak quite well. I no longer worry about minor leaks when riding.

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

Works great. Just installed my first tubeless tires. No leaks and they hold air. EDIT: A couple of months down the road, had my first experience with a cut in a tubeless tire. On an urban ride with my gravel bike and felt the tire getting spongy. Started to get worried when I added air but the tire continued to leak (could hear the leak). But, in about a minute or less, the sealant sealed the leak and I was able to continue the ride. I have since ridden a very rough 55 mile gravel ride and the tire is still holding air. Great stuff. 2nd Edit: That tire with the cut... I was able to ride it until the tire wore out. The sealed area was never an issue through several thousand additional miles. Talk about being confident. Note: I just add a bit every couple of months rather than clean and refill since I will wear a rear tire out in one season.

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.

Creates a nice seal without turning into a huge rubber ball inside the tire.

Use in all my bike tires

Works great would recommend

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.
