The K F1 series is equipped with a PTFE liner. It can withstand the most demanding applications by protecting the elastomer: acidity, alkaline fluids, and is FDA-certified for food contact. However, movement is limited and vacuum operation is prohibited.
Table of Dimensions and Mechanical Performance
The series is available in several diameters and drilling templates. The associated displacement capacities are summarized in the table below.
