Silca Removable Valve Core Extensions make simple work of inflating your tires on deep-section wheels – built to the same quality standards as Silca pumps. RVC extensions form a tight seal with elastomer gaskets and a thin film of sealant on the threads. A ribbed gasket on the outside of the extension prevents rattling and clicking inside the rim.
Made in USA from CNC 6066-T6 aluminum with elastomer gaskets. For use on tubes or tires with removable valve core. Package contains 2 extensions and tool for removing valve core and tightening extension. Available in 34 mm, 45 mm, 60 mm and 75 mm.
