Stans Tyre Sealant is a reliable and powerful sealant that is many riders first choice for tubeless conversion and flat prevention. It can be poured directly into the tire or injected through the valve stem (using a sealant injector) and quickly seals punctures up to 6.5mm. A low-viscosity formula means it can resist freezing down to -28C and it has a long and stable shelf life once opened, staying liquid for up to several months. Made from natural materials, it is safe for the environment and will not damage your tyres. Stans recommends 60ml of sealant per tyre for Road applications and 90-120ml per tyre for MTB applications. It is also compatible with tubes and tubular tyres.
