Setup, Compatibility & Care
Installation involves threading the extension clockwise onto your existing tyre valve stem until firm. Do not overtighten with pliers, as this can damage the rubber seal inside the valve. Compatibility is generally restricted to standard automotive Schrader valves; they are not intended for use with Presta valves found on some bicycles. For care, keep the threads clean and free of debris or road grime, which can prevent a proper seal. If you live in an area where road salt is used, periodically remove the extensions to check for corrosion on the valve threads and apply a light dab of anti-seize lubricant if necessary.
