    Why We Designed It | Product Specs

    Why We Designed It:

    This unique bright red gasket borrows from industries which require air-tight seals in the harshest of environments. It 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 the pressure, the tighter the seal. This design is so iconic we've found more than 20 companies world-wide making pump heads and gaskets copied from this, but none of them can come close to the precision and technology of the SILCA 242.

    New parts for old pumps!

    Theses two pumps are from the 1980's, bought both new and have loved having and using them. New gaskets every two or three years and the pumps work like new! Fast service and the right parts, buy all my parts from SILCA!

    Bravo Team Silca!

    I have had my silca pump(s) so long it cant remember not having them. This is my third gasket, and I bought the previous two were old stock from legacy bike shops. I was happy to see Silca is alive and well, and I hope they thrive!

    Quick service

    Delivered quickly as promised. Item is one of a kind and works great. Just make sure to orient it in the chuck as pictured on the listing page.

    Good Stuff

    I order these three at a time. When they are new, they work like a champ, but as the rubber wears down, they lead and do not hold the stem tightly and securely. I attribute that to the ribbed stems on the Conti tubes I use. I've used smooth stems in the past once in a while, and I bet the rubber would last longer if I used them exclusively. Average life expectancy is about 12-18 months, pumping up 2x tires 3-6 times per week. When they are new, they are great!
