Large Airlock Breast Cups
The Airlock 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.
