If you have a Pista or SuperPista pump produced after 1946, it contains this check valve assembly to ensure that the air can only flow in one direction. Most modern pumps use a rubber ball or disc and a spring, with some nicer ones using an injection molded rubber piece 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.

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. 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
