Silca Replacement Presta/Schrader Valve Chuck
The Silca Replacement Presta/Schrader Valve Chuck is a genuine replacement part for Silca pumps that builds on the industry-leading reputation for the finest quality products. The chuck is made from 17-4 stainless material that is six-times the strength of brass while the 242 gasket is five-times more durable than traditional rubber materials. This creates an incredibly durable chuck that is designed to be an heirloom piece for the cycling fanatic.
Compatible with both Presta and Schrader valves, this chuck utilises a new two-stage gasket sealing system for Presta valves and a Schrader head that is designed to create the strongest possible seal around the valve. This dramatically increases pumping efficiency as air leakage is reduced to nil.
