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.* Plus, the Stan's formula is non-hazardous, non-toxic and safe for the environment.

This 16oz bottle fills up to 8 tires.

*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.

No flats for me!
by dave

Been using this for a few years on my gravel bike. I've had punctures, but this stuff sealed them up nicely. no flats in a LONG time (knock on wood). I took the tires off the bike and noticed the sidewalls stick together making that a pain in the booty to re-install the tires. so it's not super friendly after months/years of usage.

Plugged the leak
by RedBud Rider

I had waited too long to add sealant to my tires but had everything purchased when I picked up a nail on a ride. I noticed the nail when I got home but waited to remove the nail until I was ready to add sealant. Since the old sealant was dried up, the tire immediately went flat when the nail was pulled. Once sealant was added and the tire was pumped up, the sealant filled the hole within a minute. The hole was almost large enough to require a plug, but the sealant stopped the leak!

Great Sealant
by Anonymous

I recently replaced my tubeless tire for the first time and so its the first time I have ever used tire sealant in this application. That being said, I have already tested it and it works great. I broke the sidewall of the tire while hopping up a sharp lip. I was devistated at first but when the 316 gap started to seal up I was super impressed. I thought such a large slice would surely be unrepairable but this sealant closed it right up and I have been riding on that tire ever since. Long story long, I highly recommend this product because it works

Does the job... as usual!

Works great! Fill the tire once and it's good for, well almost forever, or at lest the lifetime of the tire.

I regularly ride areas with a basketful of hazards, thorny cholla balls being most prevalent, and all I do when I get home is break off the spikes at tire level and leave them in the tire.

I just replaced a tire I wore the tread off and it still had the original fill of Stans doing it's job. When I took the tire off, the inside looked like a forest of spikes, made up of all the spikes picked up in the lifetime of the tire.

Way to go Stans!

Seals small holes and is easy to add after removal of the valve core. I've had practically no spillage.

Stans Sealant
by NA

I initially had good thoughts about this product, but I once got a nail in my mountain bike tire while riding. Out of curiosity I pulled it out and eventually the sealant sealed the hole along with some dirt sticking to it and I continued to ride on that tire for 3-4 more rides. This year, however, when I changed over to 30 mm Stans Flow MK3 rims and kept the old tires, I was unable to get all of the sealant off my tires (but most of it) and I figured the new sealant would seal it anyhow. Not so. In fact I have found that a new tire on a new rim with tape seals does better than an old tire with sealant. With the sealant I can get through a ride and lose about 10 psi of pressure and have sealant all over my tires by the end.

Stan's works really well in the tubeless tires....make sure you put enough in as it eventually does get dry. Definitely helps if you get a puncture!
