Gem 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.
