U-seals, Polypaks, U-cups

Molded in a tough urethane, this rod u-seal fits tightly in the groove while providing increased radial force on the rod.

Utilizing the same profiles as the Style 800 Polyurethane U-Seal line, these u-seals are molded from a fluorocarbon, compound. While being compatible with a broader range of fluids, these fluorocarbon seals will also operate, continuously at temperatures from -20° to +400 °F. NOTE: If you are not sure of fluid/seal compatibility, please refer, to the fluid compatibility chart in the appendix or contact our Engineering Department.

The Z-Seal™ is a squeeze type seal, combining the excellent sealability and low compression set of a resilient rubber lip with the greater anti-extrusion characteristics of a hard thermoplastic base. Under low pressure conditions, the sealing lip provides its own compressive seal force. As pressure increases, hydrostatic pressure is mechanically transmitted through the elastomeric 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. Under this condition, maximum sealing effectiveness is achieved.
