GN 817.2 Stainless Steel Indexing Plunger with Long Knob Plastic with & without Rest Position

Stainless Steel-Indexing plungers GN 817.2 correspond to GN 817, they only differ by a longer knob. Type C / CK are used for such applications where the plunger has to stay in its retracted position. To achieve this, the knob is rotated by 90° degrees after being retracted. A notch keeps the plunger in this position.
