When you rebuild a SILCA Pista or SuperPista, fit a new nut rather than reusing the old one. The nylon insert in the original nut takes a set over time and the assembly can work loose; a fresh kit keeps the pump running trouble-free for years.

Why replace the nut

SILCA's advice is simple: reusing the original nut can lead to the assembly loosening later, because the nylon insert loses its grip once it has been tightened. Swap it whenever you replace the leather piston gasket or strip the pump down for service.
