Cat® Hydraulic Cylinder Seal Kits contain all seals required for a complete reseal of a hydraulic cylinder.
Cat® Hydraulic Cylinder Seal Kits contain genuine Cat® seals, many of which feature proprietary materials and patented designs for superior compression set and broader temperature applications. All are matched to your application, helping to ensure top performance and long wear life. Also, because Cat® Hydraulic Cylinder Seal Kits provide all seals required for a complete reseal, customers are provided with a quick solution during time sensitive repairs. This ensures maximum uptime and productivity.
Cat® Hydraulic Cylinder Seal Kit application is specific to a cylinder group part number and incorporates the most recent engineering improvements.
Backup Rings prevent seal extrusion in high pressure applications, and may be used to protect the life of overall sealing system from pressure surges.
Cat® Backup Rings are designed in conjunction with the elastomeric seal and mating components, and contribute significantly to the life and performance of the sealing system in high pressure applications.
Backup ring dimensions are consistently held to tight tolerances to ensure they properly bridge the seal groove and the mating surface. Materials are selected for their pressure and abrasion resistance.
Backup rings may be solid or split. Split rings are used for ease of assembly.
Cat Sealing systems protect more expensive parts from leaks and contamination. Protect your investment with Genuine Cat Seals.
Backup rings are used in high pressure static and dynamic sealing applications, such as hydraulic pumps, valves and engine systems.
Description: O-Rings are mainly used in static application as both axial or radial seals to prevent leakage and contamination.Attributes: Cat® O-Rings are made from materials that are matched to the fluids, temperatures and pressures found in Cat® engines and machines. The materials resist wear and extrusion, and provide superior resistance to seal compression set. In addition, certain Cat® O-Rings are coated with PTFE to minimize seal twisting and cutting during seal installation.Dimensions of our O-Rings are consistently held to tight tolerances to ensure they fit properly into seal grooves with the necessary seal compression.With over 2500 O-Rings in different sizes and materials, Cat® O-Rings are your best solution for your Cat and other mobile equipment O-Ring needs.Cat® sealing system uses a robust design, testing, and validation process. Buy the latest Genuine Cat seal to protect your investment. Applications: O-Rings are used in a wide variety of applications throughout the entire Cat® product line.
Seal Shape: Type B - Double Lip Wiper
Prevents external contaminants from entering the system. Single-lip (the lip is the projecting rim or edge of the seal) wipers clean the rod as it retracts. Double-lip wipers clean the rod as it retracts and seals oil, eliminating weeping (cosmetic leakage). The double-lip wipers are secured in place with a bearing amount. These urethane wipers are metal-encased for added strength. They are often referred to as canned wipers (metal-encased) or J wipers (the metal often forms a J shape when viewed in the cross-section).
