Repair your Philips AVENT twin electric breast pump with these replacement Philips AVENT Twin Diaphragms. With regular use, the diaphragm in your pump can become worn, reducing the original suction power of your pump. Changing the diaphragm can restore your pump to peak performance so you can keep pumping milk for baby's next meal. Philips AVENT suggests replacing the diaphragms every three months--or more often, if necessary--to keep your pump working at its best.

  • Repair your breast pump with authentic Philips AVENT parts
  • Restores original vacuum power to your breast pump
  • Designed for twin electric pumps
  • BPA free and safe for baby

Included in the Box

Two Philips AVENT twin diaphragms without stems.

Philips AVENT SCF159/02 Duo Diaphrams, 2-Pack


Philips AVENT SCF159/02 Duo Diaphrams, 2-Pack

Restore Pump's Original Suction Power

After months of regular use, your pump's diaphragm can begin to weaken, reducing suction power and making it more difficult to pump as much as you want. These Philips AVENT twin diaphragms can restore your pump's original suction power, letting you keep nursing without replacing the entire pump.

Philips AVENT SCF159/02 Duo Diaphrams, 2-Pack

BPA free Replacement Diaphragms Are Safe for Baby

The twin diaphragms can replace worn diaphragms in your Philips AVENT Twin Electric Breast Pump. These diaphragms, like all Philips AVENT breast pumps and components, are BPA free to ensure your entire breastfeeding experience--from pump to storage to feeding--is free of added chemicals and safe for baby.

      Comments about Philips AVENT Duo Diaphragms 2 Pack:

      My pump was running slow and one of the flanges kept filling up with milk on the top. I bought a new set of these and i noticed a change immediately. My pump was pumping more and it was not filling up. I suggest replacing these every couple of months.

        If your pump is losing suction, try replacing these parts. I did, and went from almost none to filling three small bottles!
