Large Airlock Breast Cups

The Large Airlock Cup offers a quick method for releasing the hand pump from the breast cups while maintaining the vacuum and pressure. This cup is equipped with a high-quality in-line connector that features a built-in non-return valve, allowing air to flow in both directions until the quick-release button is pressed. Subsequently, it prevents air from escaping the cup until the airlock is reconnected. Releasing the connector takes just a few seconds.

The cup is constructed from polycarbonate material and has a base diameter of 13cm with a height of 13cm. It is designed for individuals with breast cup sizes starting from Large B or C and beyond, as well as for those with a chest size of 36 inches and beyond.
