Dimensions

FFHP quick connector is a specially designed high-pressure flat quick connector, used to replace other quick connectors in high-pressure environments. Because the flat quick connector is impervious to liquid and easy to clean, it can be used to replace other high-pressure quick connectors. Currently, there are only 3/8 body designs. Comply with ISO16028 standard
