Stans NoTubes Tire Sealant, Liquid Sealant, 2oz

Easy to use....just remove valve stem and squirt in!

I am fairly new to running tubeless tires on bicycles. The manufacturer recommends using Stans, so when it was time to replace my tires I used this sealant. I replaced the rear tire at 3k miles and the front at 4k, all with the original sealant. The rear tire was replaced after about 12 months and the front after about 18 months. My new rear tire now has 1k miles and the new front has almost 100 miles. Really happy with the performance of Stans No Tubes.

Best sealant on the market hands down !

Tired of pesky thorns or debris causing small punctures, then you need some Stans. It goes in my road bike, my mountain bike and my bikes - if it has tires youll thank me later!

Product is great but my order was wrong

Sealed up a lawn tractor tire with a slowly leaking sidewall.

Went for a ride. Got a thorn. Tire (with tube) would hold enough air to ride 50-75 yards before going flat. Poured a container of Stans into the valve stem. Spun the wheel for a bit to get Stans evenly distributed inside. Re-inflated it. Days later, still inflated. Very pleased with my purchase.

I have tried about 6 of the main sealants. I wish I would have tried this one first. This one has lasted the longest and requires less maintenance.

I use this on my road bike. It is primarily used for tubeless wheelsets but I actually put it in the tubes. I split half a 4 ounce bottle between two tubes. Remove the valve stem, put in sealant and replace stem to do this. It’s a great trick to prevent flats and I know it works because when I replace my tubes, there are marks all over the tube where it sealed. The sealant doesn’t last forever and you have to ride often or at least give the wheels a spin and keep good pressure in tires for it to work best. If tires aren’t used a lot and pressure is low, the sealant can dry up or evaporate. It’s a small issue but worth keeping in mind.

I had a basketball with a slow leak in it, I could pump it up but it was flat by the end of the day. I saw a Youtube video use this stuff and it works perfectly - I put in an inflation needle, dripped maybe 20 drops of this stuff down the needle, attached the pump and inflated and then played basketball with it. It stayed inflated and this stuff did its job almost instantly. Would totally recommend.
