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.

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.

Used interchangeably for piston or rod sealing, these u-seals employ the same tough urethane material found in our, Heavy Duty Rod and Piston U-Seals.

92A Durometer | Urethane Material | 2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.

92A Durometer | Urethane Material | 1 3/4 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.

92A Durometer | Urethane Material | 1 1/2 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

These seals are specifically designed with a second lip on their inside diameter and engineered to attain maximum, life and reliability in dynamic rod sealing. This feature results in reduced leakage, less friction, increased stability, and, prevents air and contaminants from entering the cylinder.
