Stans NoTubes Tire Sealant, Liquid Sealant, 2oz

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.

Easy use one tire.

Extremely easy and quick to recharge your tubeless tire.

Stans Race Sealant had worked quite well for me, but this stuff isnt close to as good. Just wont form and hold a seal above about 30psi as far as I can tell. The bottle is great: just the right size to carry, easy to slice open and pour through the valve stem once youve got the core out of the way. If it were full of Stans Race Sealant, it would be the perfect emergency kit carry. As it is, its kinda pointless.

great for small leaks in a tubular

Got this, along with some syringes, to repair a soccer ball that was punctured by a cactus needle. Worked great. The ball continues to hold air without a problem. Still have enough for a future repair. Quite pleased with this product!

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

Used a small amount of this on a ball with a passive leak. The ball no longer leaks. (didnt add much so it doesnt add weight or create an odd counter weight on rotation. ) I am sure this works for tires too

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.

My granddaughter received a basketball hoop for Christmas, and our daughter and I attached it to the side of a elevated clubhouse. While shooting baskets, her old nylon basketball that she had found and was proud of hit a broken-off deck screw and had a whole punched in it. She was heartbroken, and I told her that I would fix it. I looked on YouTube and found a gentleman who said to use Stans NoTubes Tire Sealant – I eventually remembered to order it, and inserted it into the basketball with a hypodermic syringe and inflator needle. I then reinflated the basketball with a bicycle tire pump. I added some more tire sealant and air a couple days later to full inflate it – is it still holding perfectly. Thank you for the YouTube video, sir and thank you for this inexpensive product- it works perfectly! 100% recommended!
