    Why We Designed It | Product Specs | Getting Started


    Why We Designed It:

    Since the 1960's all SILCA leather gaskets have come from the same leather converting house in the fashion district of Milan, Italy.  For more than 5 decades the same supplier has cut these washers from the excess material left over from the production of exotic handbags, Italian luxury cars interiors, and high-fashion luggage.  A small press is used to trim and pressure-form these leather washers into durable pressure gaskets.

    From a purely functional standpoint, inexpensive o-rings are most commonly used in this application, but no o-ring can match the smooth feel and zero-stiction action of a leather gasket.  It is common today to find SILCA leather gasket pumps throughout the professional peloton (especially during the spring classics) as o-ring seal pumps struggle with heat and often are unable to seal once the pump barrel is hot from inflating more than a few wheels.

    About as simple as it gets

    Talked briefly with a rep via the Silca site. Verified which piece I needed. Ordered and delivered. Pain free. Given the current state of the product in the cycling industry I couldn’t have asked for a easier process. My Pista is as good as ever. Thanks for making great products. Keep it up. -J

    SILCA 731 Leather Washer

    Great to be able to use pump washers from the original supplier to maintain my SILCA pump top performance. Fits 28 mm internal diameter classic Pista and Super Pista pumps (sold from 1973 - 2008), and also antique SILCA small diameter floor pumps.

    25 Year Old Pump

    Recently updated my 25 year old pump with a new leather gasket. Honestly it wasn't because it needed to be. I just wanted to ensure it would work another 25 years.
