U-seals, Polypaks, U-cups

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.

US-90URE-3-1/2×4×1/4

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 | 3 1/4 in Nominal Inner Diameter | 3/8 in Cross Section | U-Seal

The HMU style multi-lip rod u-seal combines the pressure-compensating, uni-directional characteristics of a u-seal, with the multi-lip sealing effectiveness of compression-type stacked-packings. Made from premium materials, the, HMU utilizes several sealing lip edges for dry rod performance while minimizing friction. The multi-lip design maintains, a critical sealing edge even though increasing pressure moves the line of contact down toward the heel.

Style HU seals feature a reverse bevel lip design and are molded from high quality urethane. The balanced symmetrical design makes them ideal for rod or piston applications.

90A Durometer | Urethane Material | 1 3/4 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

Style HU seals feature a reverse bevel lip design and are molded from high quality urethane. The balanced symmetrical design makes them ideal for rod or piston applications.

90A Durometer | Urethane Material | 4 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal

Molded in a tough urethane, this seal employs an additional lip near the heel. The twin lip design provides stability, friction-reducing lube retention, and some contaminant resistance. VME – Secondary lip is further from heel than standard MRTU. NOTE: E = European Urethane.
