Handsfree Cup Backflow Protector

Replacement backflow protector for your Spectra Handsfree Cups. This comes in a pack of 1, so make sure you add 2 to your cart if you need 2 sets.

Replace backflow protectors every 3 months or so, or when you notice that the diaphragms in your backflow protector look or feel 'floppy' or you notice reduction in suction.
