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.

SILCA 741 Leather Washer

Great to be able to use pump washers from the original supplier to maintain my SILCA pump top performance. Fits 30mm internal diameter Pista and Super Pista pumps (2008 and later), and also antique SILCA large diameter floor pumps.
