SILCA PART PUMP INNER CHECK VALVE ASSEMBLY

SILCA 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. Check valves generally need to be replaced every 20-25 years, and with these advancements in materials technology we hope to push that out to 30-35 years.

Kit contains: Brass Plunger, O-ring, Stainless Steel Spring and Aluminum Crush Washer.
Components manufactured in Italy and USA.
