One Airlock Kit With Silicone Tubing
The Airlock kit offers a way of quickly releasing the hand pump from the vacuum cylinder whilst still maintaining the vacuum and pressure. The kit 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 cylinder until the airlock is reconnected. The connector takes literally seconds to release. There is a length of tubing attached to both ends of the connector as shown in the picture. No other parts are necessary.
