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

Series 265, DN6.3 Steel

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

CEJN Series 265 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 265 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 265 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 10 (Series 365), DN 12.5 (Series 565), DN 16 (Series 665), DN 19 (Series 765), DN 25 (Series 065). For a stainless steel version see Series 266. Nipples with pressure eliminator available under Series 264.
