Hydraulic Products, ADX Couplings & Nipples

ADX series

CEJN ADX Series is a hydraulic Flat-Face auto-connect coupling specifically made for custom auto-dock solutions. A perfect solution for everybody that design their own automated hydraulic connection on excavator quick couplers, tractor attachments, wheel loader attachments or other mobile hydraulic applications. ADX is a true heavy duty coupling that can handle connection with pressure in the system and that is extremely resilient to surge flow. The ADX design is generic to fit different solutions on mounting and mechanical solutions on the auto-dock multi-plate. The flexible mounting gives a tolerance for certain misalignment in the connection phase as the couplings will self-align. ADX is made from high alloy steels with Zinc-Nickel surface treatment for a long life in the harshest conditions.
