NOT compatible with Legendairy Milk's Silicone Collection Cups or the Imani i2, and NOT compatible with all pumps. See below for a full list of compatible pumps.
These pink duckbill valves come with a convenient pull tab so they're easy to remove from your breast shield without risk of tearing. The durable and flexible food-grade silicone promotes strong suction when pumping. These duckbill valves are also easy to clean and can replace the traditional valve/membrane provided by some breast pump manufacturers.
Pack of 2 pink colored duckbill valves ~or~ Pack of 6 pink colored duckbill valves
COMPATIBLE WITH BREAST PUMPS:
Sterilize before first use by submerging in boiling water for three minutes.
If there is a slight gap in a duckbill when it arrives, please be rest assured that it is NOT defective. After extensive testing with a pressure gauge, we found the breast pump suction was not compromised at all.
However, duckbill valves will lose suction with regular wear and tear. Replace them every 1-2 months to ensure optimal performance. Another way to know if your duckbills need to be replaced is by doing this test:
When all your pump parts are properly assembled and your breast pump is turned on, the duckbill will pull closed at the tip. However, if the duckbill looks 'floppy' and is not closing properly when your pump is on, it needs to be replaced.
