Spectra Duckbill Valves
The duckbill valve acts as a one-way check valve in the pneumatic circuit. Over time, the silicone material loses its elasticity and the 'beak' fails to seal tightly during the vacuum stroke. This allows air to leak back into the flange, significantly reducing the negative pressure delivered to the user.

Spectra Backflow Protector
This component contains a silicone membrane that physically separates the pump motor from the milk collection kit. If the membrane is warped, torn, or not perfectly seated between the plastic casings, the vacuum created by the pump is lost to the atmosphere rather than being transferred to the breast shield.

Spectra Replacement Tubing
The tubing is the primary conduit for the vacuum; any micro-cracks at the connection points or stretching at the port interface will result in a loss of suction. Forensic evidence often shows that repeated removal and insertion of the tubing stretches the polymer, creating a loose fit that allows air infiltration.
