Hydraulic Products, X66 Range - ISO 16028 Flat-Face Stainless Steel

Series 766, DN19 Stainless Steel

  • Flat-Face design
  • Stainless steel design
  • One-hand operated

CEJN Series 766 is a Flat-Face quick-connect coupling dimensionally in accordance to ISO 16028 Standard for low- and medium-pressure hydraulic applications. The Flat-Face design minimizes spillage during connection and disconnection. The stainless steel design makes it extra sturdy to fit applications in extreme environments. Series 766 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 to prevent dust and debris from entering the system. Series 766 couplings also feature manual security locking as added protection against involuntary disconnection.

The couplings and nipples are also available in three smaller sizes; DN 6.3 (Series 266), DN 10 (Series 366), DN 12.5 (Series 566). For a steel version see Series 765. Nipples with pressure eliminator available under Series 764.
