ETP-CLASSIC R is the Stainless Steel version of ETP-CLASSIC. It is a hydraulic connection which consists of a double-walled hardened steel sleeve, filled with a specially developed pressure medium, sealing ring, piston, pressure flange and cap head clamping screws. ETP-CLASSIC type R is made of stainless steel and has hex head stainless steel clamping screws. This in order to facilitate easy cleaning, making it ideal for food processing applications.
When tightening the screws, the sleeve expands uniformly against hub and shaft and creates a rigid joint. When loosening the screws, the sleeve returns to its original measurements and can then easily be dismantled. The ETP-CLASSIC type R has a few more clamping screws, as the tightening torque is lower for stainless steel screws.
When the screws have been tightened, ETP-CLASSIC R creates an even surface pressure against the hub and shaft along virtually the entire length.
