GN818 Indexing plungers, Stainless Steel A4, with Rest Position
Stainless Steel-Indexing plungers GN 818 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.
