Remove Broken Valve Core Stems From Tires – A valve stem on a tire consists of a rubber sealed metal tube, a valve core and a valve cap. The rubber surrounding the metal tube provides an external seal to the valve stem against the rim so that air does not escape. The valve core provides an internal seal for the same purpose. The valve cap operates as a back-up to the valve core, helping to keep dirt and debris from damaging the valve core while assisting in maintaining a seal. When the valve core is damaged, you need to replace it, using a valve core removal tool available at any auto parts store.
