365 Range – Premium ISO 16028 Flat-Face Quick Couplings

CEJN Series 365 is a Flat-Face quick-connect coupling according to and exceeding the ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. Series 365 couplings require only one hand for operation, making connection and disconnection fast and easy. Dust caps are available as accessories for both the coupling and nipple when disconnected to prevent dust and debris from entering the system. Series 365 couplings feature manual security locking as added protection against involuntary disconnection.
