This unique Silca Elastomer Seal for Presta Chuck 242 gasket borrows from industries which require air-tight seals in the harshest of environments, and tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously.  New Two-Stage seal geometry seals on both valve stem and at the base of valve core threads resulting in a more positive seal and improved durability.  The new gasket slips onto the valve stem with a satisfying 'click', while unique internal geometry actually utilizes line air pressure to compress the gasket onto the valve stem: the higher you pump, the harder it grips the stem!\u003c\/p\u003e","brand":"Silca","offers":[{"title":"Default Title","offer_id":52389350473948,"sku":"ict1788108947772","price":7.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0759\/5078\/4732\/files\/silca-elastomer-seal-for-presta-chuck-242_1.png?v=1788108952","url":"https:\/\/www.rosewoodtrail.shop\/products\/silca-elastomer-seal-for-presta-chuck-242","provider":"My Store","version":"1.0","type":"link"}
