O-Rings are used in widely differing technical areas, for instance as individual sealing elements in pneumatics and hydraulics, and as preload elements for seals and wipers. O-Rings are double acting, activated by the system pressure. The sealing effect is generated by axial or radial preload. The preload of the O-Ring is superposed by the hydraulic pressure, thus assuring the overall sealing pressure.

X-Rings are used in widely differing technical areas, for instance as individual sealing elements in pneumatics and hydraulics, and as preload elements for seals and wipers. X-Rings are double acting, activated by the system pressure. The sealing effect is generated by axial or radial preload. The preload of the X-Ring is superposed by the hydraulic pressure, thus assuring the overall sealing pressure.

V-Rings are designed to axially seal bearings against dirt, dust, water, etc. in rotating machinery. The V-Ring itself rotates with the shaft.
