ETP has developed the ETP-OCTOPUS incorporating the numerous positive attributes of their hydraulic hub-shaft connections. The key benefits are the accurate positioning, quick locking, compact design and good runout. The contact surfaces will not be damaged by the joint which must be dismantled easily.

An external pressure source, which is separate from the clamping joint, is used for the ETP-OCTOPUS pressure setting. Not only does this make the pressure setting very fast, but enables several joints to be pressurized remotely at the same time. The ETP-OCTOPUS is a double-walled flanged sleeve of hardened steel. The sleeve contains bores which are used for the mounting of a scraper and hub with a screw joint, air relief screw and threaded connection for hydraulic oil. There are spiral tracks in the inner diameter which provide an even friction and defined locking force.
