This product contains:
- 2 x Spectra valve heads
- 2 x Silicone membranes
These assemble together as a valve for your breast pump and are compatible with all Spectra breast pumps. You can use these interchangeably with the Spectra duck valves, depending on which type of valve you prefer.
If you notice that your breast pump seems to have less suction or you are expressing less milk, the membranes should be the first thing you check.
Please note – the white duck valves now come with all our pumps and shield kits, and they can be used instead of the valve head and membranes.
