The one-way check valve is what lets a SILCA pump hold pressure between strokes. SILCA's brass plunger design has been in continuous use for nearly 70 years, and this kit restores a lost or damaged valve to factory spec.

Highlights

  • Classic brass 'Spillo' plunger made by the same Italian supplier since the 1940s
  • Modern O-ring seal and stainless steel spring replace the original piano-wire spring
  • Includes aluminium crush washer
  • Covered by SILCA's lifetime warranty

Built to last decades

Most modern pumps use a rubber ball or disc and a spring. SILCA says nothing matches the durability, contamination resistance and solid sealing of the brass plunger, and these valves typically last upwards of 25 years, so this part is mainly for replacing a lost or damaged assembly.

Compatibility & fit

Fits SILCA Pista pumps made since 1946, SuperPista pumps since 1989 and Impero frame pumps since 2015. Pump servicing is available as a separate Tune Cycles workshop job.

SILCA covers the Inner Valve Assembly under its lifetime warranty. For warranty support, return the product to Tune Cycles and we'll manage the claim with SILCA's Australian distributor.
