Stans NoTubes Tire Sealant, Liquid Sealant, 2oz

Easy use one tire.

Used this to fix a leaky basketball and it works like a charm.

Easy to install and helps from getting those flats in the middle of nowhere.

Great

I used 3x of these on riding-mower tubeless tire. Worked great! Holds up a month later.

Best sealant on the market hands down !

Will always have a bottle on hand

Have not got to use yet so dont know if it works. But I was told buy a friend it works.

I Had a front tubeless tire on my zero turn that broke the bead and after i got it to re-seat it had a leak. I took out the valve stem and poured the contents into the tire, pumped it up to 15 PSI, shook and rotated it to ensure good coverage to the entire inner seat, and it has held now for 3 weeks with no leakage!!

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.
