Series 165, DN5 Steel

  • Flat-Face design
  • One-hand operated
  • Extra security locking


CEJN Series 165 is a Flat-Face quick-connect coupling for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. Series 165 couplings require only one hand for operation, making connection and disconnection fast and easy. Series 165 couplings feature manual security locking as added protection against involuntary disconnection.


The couplings and nipples are also available in five other sizes; DN 6.3 (Series 265), DN 10 (Series 365), DN 12.5 (Series 565), DN 16 (Series 665), DN 19 (Series 765).
