Ultra High-Pressure Hydraulic Products, Screw-to-Connect Couplings & Nipples

Series 232, DN6.3

Series 232 is a screw-to-connect Series and a good complement to CEJN’s large range of quick connect couplings. It 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, cylinders and jacks are just a few examples of application areas.
