The head of the plunger body is provided with a suitable notch in opposite positions so as to prevent the plunger from accidentally slipping back into its forward position.
Maximum heat resistance of nylon plastic hand knob: 110°C (230°F).Indexing plungers in stainless steel, with fully threaded body, see GN 613-NI.
