Cejn 230 Series Hydraulic Couplers & Fittings
Series 230 is a screw-to-connect series and a good complement to CEJN's large range of quick connect couplings.
- The series is also characterised by CEJN's quality approach and has a high flow rate capacity.
- The series can be connected under pressure and is interchangeable with most screw-to connect couplings. Hand pumps, cylinder and jacks are just a few examples of application areas.
