Utilizing tough polyurethane, these seals possess excellent wear and abrasion resistance. Symmetrical in design, they can be used in rod or piston applications. E= European Urethane.
Urethane Material | 63 MM Nominal Inner Diameter | U-Seal
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.
95A 70A Durometer | Urethane Nitrile Rubber Material | 2 1/2 in Nominal Inner Diameter | 3/16 in Cross Section | Z-Seal
Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.
95A Durometer | Urethane Material | 3 in Nominal Inner Diameter | 7/32 in Cross Section | U-Seal
Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.
95A Durometer | Urethane Material | 1 1/2 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal
Style 850 u-seals offer excellent resistance to extrusion and abrasion. The round cross-section expander offers energized sealing from zero to 5,000 psi.
95A Durometer | Urethane Material | 4 1/2 in Nominal Inner Diameter | 7/32 in Cross Section | U-Seal
Asymmetric rod seal designed with precision trimmed sealing lips to provide a dry sealing solution in light and medium-duty applications. The Hallite 605 is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance. The twin lip design helps solve difficult rod sealing problems by providing lower friction, increased stability, and high, dynamic lip force, while preventing air penetration from outside the cylinder. Designed to have interference in the seal housing groove and has a secondary lip. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland. The inner dynamic lip is shorter and more robust to improve sealing and compression set characteristics over conventional, symmetrical U-seals.
The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are precision trimmed at an angle to give optimal rod sealing performance.
94A Durometer | Urethane Material | 3 in Nominal Inner Diameter | 1/4 in Cross Section | U-Seal
Features
- General purpose rod seal
- Robust design
- Excellent wear resistance
- Increase seal stability
- Performs well over wide temperature range and is extremely effective in low temperatures
- Primary lip protection
- Easy to install
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.
Urethane Material | 100 MM Nominal Inner Diameter | Rod U-Seal
Features
- Excellent low temperature performance
- Easy installation
Utilizing tough polyurethane, these seals possess excellent wear and abrasion resistance. Symmetrical in design, they can be used in rod or piston applications. E= European Urethane.
Urethane Material | 55 MM Nominal Inner Diameter | 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 | 1 in Nominal Inner Diameter | 5/32 in Cross Section | U-Seal
