System for Sealing Drilled Holes KOENIG SEALING AND FLOW CONTROL The Sealing Plug – a development by Koenig – is a safe, quick, leakproof, and low cost method for sealing cross-drilled holes. It ensures peak performance with a comfortable safety margin, even in extreme applications. Various types of hydraulic and pneumatic components such as controls, valves, regulators, relays, cylinders, motors, presses, pumps, etc., have one thing in common. That is that, hydraulic fluid or gaseous medium, flows through channels in the device under pressure. These channels must be drilled from outside to...

Quick Reference Pages 8 - 30 MB/CV SERIES SIDEX – SK SERIES The Sidex SK plug works on the pull/expand principle. The plug consists of an expandable sleeve around a mandrel type expanding element. By applying an axial force to the mandrel while restraining the sleeve with a special tool, the sleeve is forced to radially expand, and the serrations on the outside of the sleeve anchor into the base material of the bore wall. Upon reaching a predetermined force, the mandrel breaks off and the plug is set. LK SERIES The LK Series works on the pull/expand principle. The plug consists of an...
