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

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.

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

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.

32 oz for $13?!? Great deal and the sealant works

I use it for mountain biking. Works just as well as Stan’s, but this is a LOT cheaper.

Ive tried several cheaper options, but I'll continue to buy this one.

It’s just not my style. I like to use an injector and fill through the valve. Can’t do that with WTB. It clogs the syringe injector. I do feel it seals punctures just fine. But it’s way more work to use.

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

Product works well. Giving it a 3 ½ star cause there is n way apply through the valve. If the valve is your only option I would look for one with the applicator .
