Stan's Tire Sealant is a very thin, low viscosity liquid that coats the inside of the tire and carries with it specially formulated sealing crystals. This means that unlike foaming sealants, Stan's reaches punctures quickly and seals them effectively, from smaller holes to larger cuts.

Just two ounces of Stan's Sealant fills most road or MTB tires and the sealant stays liquid for 2-7 months on average.* And, the Stan's formula is non-hazardous, non-toxic and safe for the environment.

This single application 2oz bottle fills one tire.

*Riding in arid climates or storing the bike in a hot area will requires more frequent monitoring of sealant levels. Special anti-freeze agents allow the sealant to be used in environments as cold as -30° F.

Stans is a brand you can trust. Their sealant bottles fit easy into a valve core. Just remember to refresh the sealant 2-3 times a year. I use these small bottles when I travel with my cross bike for backup.

Used as preventative or to seal a puncture. Either way Stan's works as designed.

It really works!

I had the misfortune of having three flats in two weeks. I normally get one a year. I initially blamed my new wherlset - I was frustrated after using oodles of glue - I ride tubulars. I tried many competitor products after the puncture occurred. Stan's no tube worked amazing not only sealing hole but fixing the hole - I have since clocked 2 months without an issue - my tubular has a latex inner tube so perhaps the best combo. I since placed Stan's prophylactically in both tubulars - front and back. I ride 300-400 km wk

I have big 29 tires on commuter bike, and was getting goat head flats. Latex solution was easy to squirt in to stem w valve removed. No more leaks or flats in past 3 months.

These two ounce bottles are great for the trail
by Adam

I hardly even check my sealant, I just carry a 2oz bottle and if I spring a leak on the trail shoot up and keep rolling. This plus co2 of course, to reseat the bead if needed.

Then I can actually refill the little bottle and use saran wrap to create a good seal for next time.

Put this in your road tubulars and resist all but the worst punctures. I've pulled thumb tacks from my tire and kept on riding... Great stuff.

Seal it up!
by Scott

I've been running tubeless on my mountain bike for a few years now and I haven't had a flat or issue. You can run low pressures that would normally guarantee a flat with tubes, but not cause any issues with tubeless. When the tire starts to run low after sitting for a few days (like mine did) you squirt it thru the valve stem with the handy dandy top of the container and voila your back in the game.

Works deponds on the size and form
by ss

Works on punctures and cuts less than 1 mm.

Works better on puntures compare to cuts.

Borderline on 1-2 mm cuts. May be ok for same size (1-2 mm puncture)

Does not work on cuts more than 2 mm. 2mm cut under pressure it will fail.

You can wipe out the liquid easily if you make a mess. even without water. Doesn't stick or leave stain on your cloth after washing.

I recommend this product because if you can't fix the flat with this you won't be able to fix it with Vittoria pit stop either. Yet Stans is alot cheaper.

I wrote a comment on Vittoria pit stop if you are interested.

I had bought Tufo sealant also but have not tried it yet.

Good backup for travel
by Anonymous

If you have multiple sets of tubless wheels, or frequently refresh your sealant, the large jug of Stan's sealant is more economical and eco-friendly. However, these little 2 oz shots are good to carry on travel for backup, or while riding for emergency repairs. You can also re-use the bottles to ensure you're adding consistent doses of sealant from the big jug to your tires. With higher volume tires (e.g., 29 x 2.2-2.4), I need 3-4 oz for a good initial tubeless seal. For lower volume road tires, one 2 oz bottle per tire should suffice.

Tubeless goo makes me happy
by Roly-poly

This is the perfect amount to turn one wheel into tubeless. The big bottles typically dry up before you can use it all, unless you work in a shop or are setting up a bunch of bikes with tubeless. You need a tubeless capable tire and rim. I have run tubeless from the first year mavic came out with UST. Back then stans' wasn't a good product, now it is great. Running this with my UST rim strip and UST capable tires saves tire weight (good place to save weight on a bike) and still allows me to run 25psi on my 2.4/2.2 tires. I had a thorn on my second ride using this and sealed up and I didn't have to throw away a brand new tire.

If running tubeless this is definitely the way to now

The right does
by Anonymous

At first, I balked at buying single-shot sealant. However, the small bottles are great if you have to re-seal tires during travel and don't want to pack a jug of sealant. Also, this packaging gives you the right dose for a single tire with the right amount of sealant particles in each dose...BTW, the stuff works. One of my tires (Schwalbe Rocket Ron) recently took a beating on rocky terrain. The sealant plugged several small holes so well that I didn't even notice the damage until I spotted little patches of sealant mixed with dirt stuck to the outside of the tread. Any ride where I don't have to waste time futzing with flats is a good ride.

So Far So Good

I've been riding with Stans NoTubes on my road bike with latex tubes for several months, and have had no flats. I did have a puncture - the dreaded hiss - and looked down to see the white Stan's latex squirting out, and thought it had failed. But a few seconds later it worked its magic, sealed up, and I had enough air pressure remaining that I didn't need to stop, and wasn't dropped by my fast group ride.

Very convenient to squirt into the tire valve. I'll keep a single use container for future measurement and buy a large bottle to refill it. Nice to know that after a puncture, I can re-inflate my tubular and still get home, at speed.
