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 32oz bottle fills up to 16 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.
