US-90URE-1-3/16×1-9/16×1/4
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 | 4 in Nominal Inner Diameter | 3/16 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

Machined from 1018 Carbon Steel for a 2 in cylinder.
The length is 0.5 in and the lip is 0.25 in in tall.
Base plates are welded to the end of the cylinder opposite the rod end to secure the cylinder. They provide a solid support for the entire cylinder base area.
Wipers are installed in hydraulic cylinders to prevent dirt, dust, and moisture from entering the cylinder as they retract back into the system. A hydraulic wiper prevents contamination that could damage wear rings, seals, and other cylinder components.

Features
- Installed in hydraulic cylinders to prevent dirt, dust, and moistures
- Hydraulic wiper prevents contamination that could damage wear rings, seals, and other cylinder components
Wear rings provide a hard-wearing surface that protects the cylinder walls and the piston rod from scoring and abrasion. By maintaining alignment and reducing side loads, these rings facilitate smoother piston movement and lower friction levels.
Nylon Material | 2 1/8 in Nominal Inner Diameter | 1/8 in Cross Section | Wear Ring
Features
- Protection Against Wear
- Reduced Friction
- Extended Cylinder Life
- Operational Efficiency
Hytrel backup ring with a flat cross-section.
Molded of 55D Durometer Hytrel, these back-up rings provide excellent extrusion resistance and tolerance to fluids such as phosphate esters, hydraulic oil and water. Stretched for installation, they return quickly to their original size for easy installation.
