iMEDiHelp Airlock Tubing Kit
These unique airlocks for the nipple cups enable the user to pump up the nipples and then remove the hand pump and tubing whilst leaving the nipples pumped up. It can be used with both silicone tubing, and similar to clamps, allows the pump to be disconnected without a loss of vacuum. Airlocks act as a connector between two lengths of tubing. A return valve allows air to pass in both directions while the airlock is connected but once the quick release button is pressed, the tubing is separated but the valve closes and prevents air from escaping until the airlock is reconnected.
