Limited Warranty

SILCA LIMITED WARRANTY 

Parts covered by SILCA Limited Warranty are considered to be subject to wear through normal use or are consumable subject to degradation through the course of their daily use.  SILCA guarantees the life of these items to be at least 2 years from the date of original purchase.

    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.

    Gasket (731) Replacement

    Watched both Silca videos, and easily made a successful replacement, using the oil & saturating the gasket, then installing.

    The video tips were very helpful, and pump is working like new. Appreciated the quick & great customer service.

    Exact fit.

    I replaced the Gasket in my 2001 Super Pista. I followed the instructions in the video. After conditioning it with NFS Leather Conditioner and Pump lubricant, it fit very tightly into the pump. The entire process was easy and now my old pump works like new.
