Replacement duck valve for Handsfree Cups of your Spectra. They are not compatible with your Spectra shields, as they are smaller in size and will not fit.
If you notice reduced suction when pumping, this is often the first sign that your valves for handsfree cups need to be replaced. If you are pumping regularly, you should replace your valves at least every 3 months.
The top of the valve for handsfree cups is quite delicate and can be susceptible to fraying or tiny tears; if you notice reduced suction or lower milk output then examine this area carefully.
It will last longer if you avoid cleaning them in the dishwasher or sterilizer.
