The Product that Started a Tubeless Revolution
Inside this simple black bottle is a product that changed cycling. Today's tubeless systems rely on the lighter, more reliable, self-sealing performance of Stan's Tire Sealant.
Just two ounces of Stan's in a converted standard tire or tubeless tire can repair punctures up to 1/4-inch almost instantly to keep you rolling. Longer-lasting Stan's Tire Sealant is formulated to stay liquid in tires with even thin casings for up to seven months. Arid conditions require more frequent monitoring of sealant levels, but anti-freezing agents in our special formula allow Stan's Tire Sealant to be used in temperatures as cold as -30° F. One quart will convert up to 16 tires.
- First choice of riders around the world for tubeless conversion and flat prevention
- Seals punctures up to 1/4-inch (6.5mm) quickly
- Stays liquid 2-7 months for long-lasting protection
- Premium low-viscosity formula resists freezing to work in environments as cold as -30° F (-34° C)
- Natural materials, safe for the environment
- Can be injected through valve stems with removable cores compatible with tubes and tubular tires

Does what it is supposed to do like most sealants. It does need to be replaced periodiacally. They recommend 6 months but I have found it lasts about one year
Have notice a coagulated mass in two tubes after a couple of years in use.
We use Stan's Sealant in both road bike tires (with tubes) and mountain bike tires (tubeless). Here is the [...] area, punctures are just a part of life, but flats while riding do not have to be. In the last decade, we have had hundreds of punctures, usually thorns from the many [...] flora here who have them and they all seem to.But, we have had to change a tube on the road only two or three times and never in the dirt. Yeah, getting sprayed as the sealant begins to seal the puncture is not something we look forward to. Cleaning the resulting mess off the frame after we ride home is also a leat favorite chore, but it beats changing a flat.Be sure to take along your CO2 inflater. Sometimes enough pressure escapes before a seal is acheived that you will need to re-inflate to get home. And keep moving, if you can to distribute the seaalant or stop with the puncture at the bottom of the wheel to ensure sealant reaches the hole.
