CEJN® Series 562 Couplings

  • CEJN Series 562 is a Flat-Face quick-connect coupling that dimensionally interchange with the ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. Series 562 is a range of products suitable for applications with less stringent demands. The series 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 to prevent dust and debris from entering the system. Series 562 couplings also feature manual security locking as added protection against involuntary disconnection.

  • The couplings and nipples are also available in three other sizes; DN 6.3 (Series 262), DN 10 (Series 362) and DN 25 (Series 962). For a steel version in accordance with ISO Standard 16028 see Series 565. For a stainless steel version of the standard see Series 566. Nipples with pressure eliminator available under Series 564.
