Inner Valve Assembly
SILCA LIMITED WARRANTY
Parts covered by SILCA Limited Warranty are considered to be subject to wear through normal use or are consumable subject to degradation through the course of their daily use. SILCA guarantees them free from manufacturer defects for 2 years.
What is it?
If you have a SILCA PISTA made since 1946, a SUPERPISTA since 1989, or any of the Impero Frame Pumps since 2015, it contains a check valve assembly like this to ensure that air can only flow in one direction.
Who's it for?
As these check valves typically last upwards of 25 years, these service parts are typically to remedy lost or damaged valve assemblies.
Why We Designed It | Product SpecsWhy We Designed It:
Most modern pumps use a rubber ball or disc and a spring. Some nicer pumps use an injection molded rubber plug and spring, but nothing has the durability, contamination resistance, or solid sealing action of this brass plunger design which has been in continuous use for nearly 70 years.
The supplier for the brass plunger has been the same since the 1940's.  This beautiful shop is run by 3 brothers outside of Milan Italy, who are carrying on the legacy of their grandfather. The brothers are very pleased to keep the tradition of excellence and craftsmanship passed down for generations moving forward today, which is why we continue purchasing these parts exclusively from them.
We have chosen to update this rebuild kit by matching the classic 'Spillo' plunger in brass with a high-tech O-ring and stainless-steel spring replacing the original piano-wire spring.
