This kit contains the hardware required to support a leather gasket in all SILCA floor pumps. Reusing the original 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.
Kit includes 5 parts:
- Locking Nut, lower washer, and back nut are universal to all PISTA and SUPERPISTA Pumps
- 28mm diameter or pumps prior to 2008 will use the thicker 24.6mm back washer
- 30mm diameter or pumps after 2008 will use thinner 28mm back washer
