The Z-seal is a squeeze type seal primarily used for heavy-duty rod applications. This seal combines excellent sealability, low compression set and superior anti-extrusion characteristics when compared to other lip seals. Under low-pressure conditions, the sealing lip provides its own compressive sealing force. As the pressure increases, hydrostatic pressure is mechanically transmitted through the elastomer seal element into the anti-extrusion base. The applied force then deflects radially in a controlled manner, closing the extrusion gap behind the sealing lip. The various Z-seal configurations are designed to accommodate standard groove dimensions with normal manufacturing tolerances. Z-seals fit into standard deep loaded U-cup glands. For groove dimensions please reference the loaded U-cup section.
Z-seal part numbers are based on a Nitrile sealing lip and Urethane base. Parts containing a different material use a suffix to represent the used material. |  |
