CEJN / Series X65

 Print This Page

Series X65 couplings meet design requirements for ISO 16028, an international standard that specifies interface
dimensions for interchangeability and performance requirements or hydraulic, flat-face, quick-action couplings at pressures from 25 MPa to 31.5 MPa.

Low Spillage during Connection and Disconnection
The flat-face design of Series X65 couplings minimizes spillage during connection and disconnection. And the smooth,flat surfaces of the couplings are easily wiped clean, further reducing spillage and the threat of contamination entering hydraulic systems.

One-Hand Operation for Easy Connection
Series X65 couplings require only one hand for operation, making connection and disconnection fast and easy. During connection, the coupling and nipple automatically lock into place.

Security Locking for Extra Protection Against Involuntary Disconnection
As added protection against involuntary disconnection, the coupling design includes a manual security-locking feature. It is engaged by manually turning the locking sleeve after connection. The lock is released by returning the sleeve to its original position during disconnection.

Optional Dust Caps Available
To prevent dust and debris from entering the system, dust caps are recommended for use on both the coupling and nipple when they are connected and disconnected. They are available for all sizes and connections (see part numbers on the following page).

DN 6.3 (1/4") to DN 19 (3/4") Sizes
Series X65 couplings are offered in the following size ranges, making them suitable for a wide variety of applications: Series 265 – DN 6.3 (1/4"), Series 365 – DN 10 (3/8"), Series 565 –DN 12.5 (1/2"), Series 665 – DN 16 (5/8") and Series 765 – DN 19 (3/4").

Two-Part Design
Since the two-part couplings feature separate front and back sections, standard line products are available with custom rear sections or threads to meet specific application requirements.
