ETP-EXPRESS is a hydraulic connection which consists of a double-walled hardened steel sleeve filled with a pressure medium and a flange. The flange part contains screw and piston with seals to maintain pressure.
When the pressure screw is tightened, the double-walled sleeve expands uniformly against shaft and hub and creates a rigid joint.
Dismantling is done by loosening the screw. ETP-EXPRESS returns to its original dimensions and can easily be dismantled.
