CEJN / Series 525
Vendor: CEJN
Coupling Type: Hydraulic Couplings & Adapters
Description:
Couplings for Mobile Hydraulics
Coupling Category:
No Spill Flat Face Hydraulic Couplings
CEJN's Series 525 couplings offer a heavy-duty design for mobile hydraulic
applications, plus added protection against involuntary disconnection.
Chrome-Plated Steel Couplings in a Standard,
Heavy-Duty Design
Series 525 features a heavy-duty design with chromeplated steel as standard. All parts exposed to extreme strain and stress, such as the locking sleeve and nipple, are made of hardened steel for extra protection. These materials ensure that the couplings offer rugged use and a long service life.
Extra Sealing Capacity
Double O-rings and a backup ring give Series 525 improved sealing performance.
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 disconnected. They are available for all sizes and connections.
DN 6.3 (1/4") to DN 25 (1") Sizes
CEJN 525 couplings are offered in sizes from 1/4" to 1", making them suitable for a wide variety of applications.
Optional Pressure Eliminator
Both the nipple and coupling are designed with a built-in pressure eliminator, allowing a low-force-to-connect operation, even when either half is under residual pressure.
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 black locking ring after connection. The lock is released by returning the ring to its original position prior to disconnection.
Technical Data
Material Coupling: Steel (yellow zinc chromate plating)
Material Nipple: Hardened steel (yellow zinc chromate plating)
Seal material: Nitrile
Temperature range: 30° C to +100° C (-22° F to +212° F)
