Since our fittings are simply plugged in, you don’t have to worry about hand-tool clearance. Traditional screw to connect fittings require extra space when tightened, but WEO will make it easier for you to build a compact and reliable hydraulic system. With WEO at the drawing board stage, you also cut time on the production line.

On the production line: CEJN WEO Plug-In hose fittings reduce downtime and installation time for equipment manufacturers. The click-to-connect and self-aligning features of the fittings make them easy to install in hydraulic systems, dramatically reducing costs through their quick installation time. Once it has been plugged in, the fitting locks into place, eliminating the need for tightening during follow-up security checks. The tight connection also gives you leak-free connections.
