Silca

Leather Piston Gasket, #751

Silca Leather Piston Gasket #751 is a direct replacement piston seal for compatible Silca floor and frame pumps, restoring smooth, efficient pressure build and the signature feel that made classic Silca pumps a long-term service item instead of a disposable tool.

Hand-produced in Milan, Italy from 2.5mm full-grain leather, this gasket is the same style used across Silca’s Pista lineage for decades—chosen for consistent sealing, durability, and reliable performance across a wide range of pressures when properly lubricated and maintained.

• Correct fit for 19mm pump barrels - Designed for 19mm internal diameter Silca pumps, including post-2015 Impero Frame and Pocket Impero pumps
• Full-grain leather sealing surface - Conforms to the pump barrel for an effective seal and efficient stroke, helping reduce slip and lost pressure
• 2.5mm leather thickness - Built for long service life and consistent engagement under load
• Made in Milan, Italy - Hand-crafted replacement part aligned with the traditional Silca pump service standard
• Service note - Reusing the original locknut/nylon-insert hardware can loosen over time; replacing the bolt kit during service helps keep the piston assembly secure
