Information

GN 818 Stainless Steel-Indexing plungers are set apart by the materials used, allowing these plungers to withstand particularly corrosive environments.

Indexing plungers with a rest position are used for such applications where the plunger has to stay in its retracted position. In that case, the knob is retracted and afterwards turned by 90°. A notch keeps the plunger in this position.
