The Extra Extra Large Airlock Breast Cup offers a way of quickly releasing the hand pump from the breast cups whilst still maintaining the vacuum and pressure. The cup consists of a high quality in-line connector which has a built in non-return valve. This means that air will flow in both directions until the quick release button is pressed. Then, air is prevented from leaving the cup until the airlock is reconnected. The connector takes literally seconds to release.
The Extra Large cups measure 15cm wide and 17cm high.
Base diameter = 15cm.
Height = 16cm.
For breast cup size D onwards.
1 Year Warranty.
Customer reviews
one of these cups holds pressure very well, and one always loses pressure and will not keep pressure, it leaks down, and I have to keep pumping it back up over and over. other than that I love these cups.
