Stans NoTubes Tire Sealant, Liquid Sealant, 2oz

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

Four yrs ago I took a bike trip down the west coast and I had 3 flats in 3 days. I stopped by a bike shop/store an they recommended STANS. I put in another bottle of STANS every 4 months and have had on one flat since using it. An ride between 8,000 to 9,500 miles a year.

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.

Will always have a bottle on hand

Easy use one tire.

This is a single 2 oz bottle unlike the description saying 12 pack. When it seems too good to be true, it usually is.

I put this in my 700 c tubes and still got a flat, sealant was all over my tires, wheels and the tube was covered in slime. Does not work in tubes.

I used this to stop a slow leak in my compact tractor tire. It was easy to apply and fixed the leak. I recommend this sealant.

This 1 oz bottle is great to pack for backup on tubeless tires. I hauled mine around for a few years and it still worked when I needed it. Useful for on the trail and you have mysterious leaks, or a puncture to replenish any lost sealant. The one caveat, with modern MTB tire widths, you may want to carry 2. Depends on how often you get punctures or how frequently you check your sealant level in your tires. Youll need at least 1 bottle/tire for any fixes. More if you totally lose the existing sealant. One note, keep an eye on the little cap. Without that theres nothing to prevent a mess in the pack after usage, not to mention reusing the bottle.

Great for my mountain bike tires. I could have sworn the thorn I got was large enough to leave me stranded but this stuff sealed up the hole no problem.
