Unior Valve Core Remover Removing The Core A valve core remover tool is designed to. . . remove valve cores. With the core of your valve removed, you can easily add tubeless sealant or replace an old core with a new core. The Unior Valve Core Remover is made out of tool steel and is perfect for the workshop. It's about 80mm long and 10mm in diameter, so it's big enough to feel good in your hands, big enough to not get lost in the bottom of your toolbox, and small enough to easily work within the confines of a wheel.
