Duckbill Valve and O-ring Seals

Gem Pump Duckbill Valves create the suction in the Gem Pump and ensures
that your milk only flows one way - into the milk collection bottle. 

The Gem Pump O-ring Seals are used to ensure efficient sealing and prevent
leakage in your Gem Pump.

• Made from food grade silicon.
• Included: 2 x Duckbill Valves and 2 x O-ring Seals.
• If your Gem Pump Duckbill Valves or O-ring Seals are damaged or have a tear
  or a whole, they are unable to create the necessary suction and seal in your Gem Pump and these damaged parts will therefore need to be replaced.
