Abstract
A vacuum pump () has an inlet () and an outlet (). Plug-in screw fittings () are connected with the inlet and the outlet. The plug-in screw fittings include a bore with an internal bevel () that receives a flexible connecting line (), a chuck collet (), and an O-ring () frictionally in a vacuum-tight relationship. In this manner, a more simple and versatile connection is provided between the vacuum pump and the connecting lines.
