Award winning tire sealant from the folks that invented tubeless conversion and redefined puncture protection.
Unlike other tire sealants, 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. The low viscous nature allows the sealant to quickly reach the puncture site and the crystals aid in sealing large holes, something which thicker or foaming style sealants cannot claim.
Stan's Tire Sealant will stay liquid in a mountain bike tire with a thin casing for 2-7 months on average. 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.
A fresh new look to the packaging but the same great sealant within. Stan's Tire Sealant has always been non-hazardous, non-toxic and safe for the environment so we decided it was time to make that fact a little more well known.
