This is the connector assembly that goes between the bottle and the breastshield. This is made up of three small pieces (the hard plastic case and the rubber diaphragm) all connected as one piece.
The bottles screw onto the bottom, the tubes connect, and the breastshield connects to it.
Price is for one item. If you have a double pump and need two replacements please change your cart quantity to 2.
