Why it lives in the nook

Duckbill valves soften, backflow membranes stretch and tubing clouds over. These three are responsible for most “my pump got weaker” moments, and swapping them takes about a minute.

  • Six duckbill valves With a grab-pull tab, so a worn valve comes off and a fresh one goes on in seconds.
  • Backflow protectors and membranes Two of each: a closed system that keeps milk out of the tubing and away from the motor.
  • Two 41-inch tubes Longer than the originals, so the pump can sit further away on the table.
  • Food-grade silicone Made by Nursi Luna, not original Spectra parts; BPA-free and fine to boil or steam.
