CEJN's screw to connect couplings for high-pressure hydraulics consist of couplings in two sizes that are interchangeable with most screw-to-connect couplings and nipples on the market. The couplings can be connected under pressure and are well suited for hand pumps, cylinders and jacks, just to mention a few applications.
