SuperPista Check Valve Assembly

This Silca SuperPista check valve assembly features a time-proven brass plunger mechanism refined with modern materials, a high-tech O-ring and stainless steel spring replace the original piano-wire design. Manufactured for unidirectional airflow in Pista and SuperPista pumps manufactured post-1946, the robust brass construction resists contamination and delivers superior sealing performance. With these material upgrades, Silca extends service intervals from 20-25 years to 30-35 years, maintaining the legendary durability that defines this 70-year-old design.
