If you are rebuilding your older SILCA Pista or SuperPista pump with a new leather washer, you might consider also using this updated washer and nut kit. Reusing the original nylon inserted nut can lead to later loosening of the assembly as the nylon insert will take a set over time. A new bolt kit guarantees years and years of trouble free service. This kit uses only nuts and washers from a factory in Ohio which SILCA chose for their class leading environmental policies and ultra-low energy galvanizing processes.
The SILCA Nut and Washer Kit contains 5 parts. The locking nut, lower washer, and back nut, are universal to all Pista and SuperPista Pumps.
Pumps produced prior 2008 use the thicker 24.6 mm back washer.
Pumps produced after 2008 will use the thinner 28 mm back washer.
Included in delivery: 1 locking nut, 1 back nut, 3 back washer
