Orange Seal  Endurance Sealant - 8 fl. oz.

I have only been using Orange Seal Endurance Sealant for about 2 years. So far my experience is better than with other sealant products on road bike tires. In particular the duration of maintaining inflation on occasionally ridden bikes is better. The fact that a filler tube is provided with the bottle is a plus. I have yet to remove an Orange sealed tire, so can't comment on the nature of the dreaded "stanimals" that may deposit with this product. This is my first application of Orange Seal Endurance on MTB tires, so am hesitant to give a full 5 star rating, until I have more time on the trails.

I ordered this product 11/25/2024 and received it on 11/29/2024. Arrived much sooner than expected. Kudos to REI and USPS for quick order processing and shipping. Why only 3 stars? REI shipped the bottle of sealant without the requisite cap that accommodates the injector tube that gets the sealant into the tube/tire. The bottle I received has the injector tube banded to the bottle, but no cap. Fortunately,I don't have an immediate need to use the sealant. I have no doubt about the quality of the sealant. That said, I'll scour the local bike shops for a bottle that has all the requisite parts and buy it.

Works as advertised, although a bit difficult to gauge amount inserted as there are no amount marks on the bottle and fluid foams up a bit when injecting into tire.

This is the only product I use. I love it! Except, it ruined my brand outfit once when I got large puncture on a tire and it splattered all over me and my bike. I could never get the stains off. However, I still love this product!

I bought this a few years ago as a first time tubeless convert. The clerk at the store recommended it. After about 3000 miles mountain biking, I can say that I've never had a problem with it. But then I don't recall ever getting a puncture ***that I was aware of***. Mission accomplished, I guess. The tires wore out. I replaced the fluid every year or two. So I bought some more to re-do my mountain bike and (finally) convert my gravel bike. My guess is that whatever brand REI sells, it's gonna work out pretty good.

Reliable! Easy to refill. Really glad I made the switch to tubeless.

I was setting up my Topstone tubeless and after seating my tire, I added the Orange Sealant. I inflated the tire again and there was absolutely no air leaking out. I let the tire sit overnight and there was no loss of tire pressure. I could not believe how quickly this sealant worked. From now on I am using this on all of my tires. It is amazing!

Works well. Better than Stan's and other competitors, which don't seem to do anything when tire is punctured unless you're fast enough to plug.

Very good sealant. Seals pretty much every puncture - I would highly recommend. I’ve tried a few others (namely Stan’s and Muc-Off), and Orange is significantly better at sealing punctures. Just need to put in sealant more frequently since it tends to evaporate and leave moisture in the tire casing.

Seals well with tire install, but won’t fill punctures well. I think they are trying to go too light on the latex crystals.
