Screw-to-connect couplings & nipples

Series 230 - DN7

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 characterized 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, cylinders and jacks are just a few examples of application areas.
