Stan's NoTubes Original Tubeless Sealant – 1000ml

Stan's Original was the first tubeless sealant in the world, formulated by Stan in 2001, and is recommended for all-around use with tubeless road, gravel, and mountain bike tires. It seals punctures up to 6.5mm (1/4 inch), remains liquid inside tires for 2–7 months, and anti-freezing agents allow use in temperatures down to -20°F. One liter can seal up to 16 tires and can be installed through the valve using Stan's Tubeless Sealant Injector.
