Topeak Presta Valve Extender is machined from durable aircraft grade aluminum alloy, to conveniently extend length of two-piece type presta valves to aid inflation. Durable aluminum alloy valve tool is designed to easily tighten or remove two-piece type Presta valve cores and valve extenders. Comes packed in a blister pack with 2 valve extender and valve tool. The valve extender is inserted between the valve body and valve itself. Use the valve tool to remove the inner tube original presta valve core, install the valve extender and use the valve tool to tighten the valve stem. The original valve core gets threaded into the tip of the Topeak valve extender and use the valve tool to tighten it. This type of valve extension makes for easy inflation, tire pressure adjustments or deflation because the pump attaches to the original valve, not the extender.
