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

Switched to WTB sealant, only thing that works in their tires. Added 4 oz to my Sendaro front tire a year ago, stopped working recently. Pic shows what you get when it's dried up, a solid rubber puck that literally was sliding around in the tire, unattached. Added another 4 oz, I figure 6 months is a max. This bike doesn't get a lot of use, and is in my AZ garage in the heat, so probably longer elsewhere. Infinitely better sealant than Stan's, which is a total mess after a few months.

After using an entire bottle over 10 months in 3 bikes (Enduro, xc,road), here's my thoughts. While I've used 4 different sealants over the years, I'm primarily a stans user, so I'll compare it to that. It worked okay for punctures. It seemed like all punctures took longer to seal versus stans. Nearly all punctures required plugs. Stans for me stopped more smallish punctures while riding. Wtb sealant never sealed instantaneous, I would have to hold the tire puncture side down and hope it would seal or plug it. Occasionally adding air to 24psi would break the freshly sealed puncture too. Stans lasts a whole lot longer than wtb. Wtb requires refreshing the sealant periodically while stans was good to go for many, many months. I experienced strange clumping action within the tire too, the latex didn't seem to want to stay suspended in the fluid once in the tire. Overall I wasn't impressed. I rather spend the extra 6 bucks for a stans 32oz bottle and have a more consistent experience. Wtb's sealant levels were unpredictable, especially in the summer months(I live in dry NorCal). I wanted to like it, but after the bottle I'm off to trying something else. I like stans, the price has driven me to give other sealants a try, but so far nothing is as good as stans.

As advertised, pleased with this item.

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

Well it did work I won't ever buy this again when it arrived I'm not sure if it was frozen or what the issue was but I shook it for more than a minute as the instructions indicated I used a typical shrimp that you would use to fill your rim through a press the valve and it clogged instantly this stuff was incredibly clumpy I even put it into a mini blender to see if I could break the particles down and it was no better. I'll stick to Stans product

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

meh

I used it to repair a 2018 WC soccer ball in conjunction with marinade injector needle and it worked perfectly! Inject fluid, 20mls, roll ball around and then inflate it. Still holding air more than a week later!
