KGD-AE PISTON SEAL
– Two internal anti-extrusion rings with stabilizers which prevent rotation of the sealing element Rubber. Special grooves with a special geometry ensure that the pressure can energize the central estate without risk that this can extrude.
– Two anti-extrusion rings that allow high play of coupling or structural deformations without the danger of extrusion, ensuring thus a long life of the various components.
