Koenig SK Series Expander

Boneham Stand: K34

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.
