Hydraulic Products, X65 Range - Premium ISO 16028 Flat-Face Quick Couplings

Series 065, DN25 Steel

  • Flat-face design
  • One-hand operation
  • Extra locking security


CEJN Series 065 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 065 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 065 couplings feature manual security locking as added protection against involuntary disconnection.


The couplings and nipples are also available in other sizes; DN 5 (Series 165), DN 6.3 (Series 265), DN 10 (Series 365), DN 12.5 (Series 565), DN 16 (Series 665), DN 19 (Series 765).
