- Tubeless Bike Tire Sealant (4 oz to 1 Gallon) - Quick Seal for Punctures up to 6mm - All Conditions

We’ll I don’t know what to really say about who is best at sealing a hole, there’s are lots of videos of people poking holes in tires and spinning them and that’s just bogus example of how they seal, the tire spins and slings sealant to the hole they made in the outer part of the tire, gravity made the sealant fling out to the hole, on a slow gravel ride going 6-8 mph up a hill isn’t gonna sling anything around, the puncher passes the sealant which is puddled at the bottom of the tire and has little time to seal the hole, also the tire is flexing and making the punch open and close, deforming the hole, which smushes the sealnat out the hole, also the sealnat doesn’t work the same on pavement compared to gravel, so my advise it buy loads of different brands and see what works in your tires and the surfaces you ride I know this doesn’t sound like any help, but it’s true, I have had best results with Stan’s no tube sealant, not because I think it’s the best sealnat, but because it does a great job but doesn’t coat the inside of the tire with latex, I change tires a lot putting different ones on for different rides and I can wash the inside of my tire and set aside and reuse it again, a lot of sealant is truely latex paint and it forms plastic rubbery layer in the tire and rim, and is impossible to remove So that’s why I use the Stan’s I thought I’d try this product it compare but haven’t had a chance to see how it’s gonna do compared to others yet sorry but I hope this helped

This sealant works great. I've been using it for almost two years and just finished off my 1st liter. I'm writing this review as I'm reordering another liter. I haven't had a flat while riding since i started using this. It has sealed everything quickly. The only time it has dried out is if i let a tire go flat after months in winter storage. It's easy to use and easy to remove when changing tires. It's ammonia-free. Despite other reviews saying you can't inject it, I haven't had any trouble putting this in through the valve each time with an appropriately sized injector. It makes tubeless set up easy.

Did a great job of getting my tubeless setup going. Too bad Aventon did a piss poor tape job on my "tubeless ready" rear wheel. Leaks in EVERY spoke. Thankfully they made good and ponied up the $40 to get my rim re-taped locally. Another batch of WTB sealant, mounted the tire, aired it up...ALL GOOD!!! This is great stuff for the money. HIGHLY RECOMMENDED!!!

I’m sold on this stuff. It sealed a sidewall tear I got on a ride, and kept my tire pressured just enough to get home. Of course I replaced the tire but this stuff is durable. I rode through a couple streams of water after that tire tear and it still kept a seal. Very easy to clean up! It does not come with an injection tool, so unless you’re planning on just pouring it, you’ll need to get one of those!

It seals holes well and the price is reasonable. Only downside is it contains a lot of fibers which makes it harder to inject through valve (core removed). It also becomes messy balls after year or so inside the tire. Cleaning once a year is needed.

My tubeless tire was leaking air slowly and the sealant filled the gap. Happy rider

Excellent quality

Good quality and the nozzle on the top makes it easy to apply because you don’t have to take the entire wheel off, you can just remove the valve stem.

Rear tire kept losing air and after pouring in the recommended amount, it stopped

Unmöglich über Spritze & Ventileinsatz einzufüllen! Die Teilchen sind zum Teil so groß dass sie sogar das Loch zwischen Felge und Ventil verstopfen!

I went tubeless for the first time using this stuff. Sealed well, hasn't leaked any noticeable amount of air in months.

meh

.. aber sie war bisher die einzige, die zuverlässig Vittoria Terreno dicht bekommen hat! Ich nutzte bisher Stan's und war recht zufrieden, außer den üblen Gestank. Die WTB Milch riecht angenehmer und hat wohl kein Ammoniak.
