Sludge Pro Series sealant is designed for presta valves, and getting the Sludge into the tube couldn’t be simpler as it is thin enough to flow through a presta valve.

We would advise following the instructions and using petroleum jelly on the valve, as this helps to keep the valve clear. Each bottle contains 100ml, enough for two tyres.
