Overview
The Koenig Series CV 173 imperial expander plug effectively seals drilled holes with complete reliability. Expansion technology forms a complete metal-to-metal seal as the stainless steel ball is pressed into the aluminium sleeve. The CV 173 inch is ideal for projects measured in imperial. Metal-to-metal expander technology removes the need for any sealants, adhesives, or rags, reducing lifetime costs of the seal and improving sustainability.
