Remanufactured part
O-ring
Description:
O-Rings are used in static sealing and some dynamic applications.
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 systems protect more expensive parts from leaks and contamination. Protect your investment with Genuine Cat Seals.
Applications:
O-Rings are used in many static and dynamic joints throughout Cat machines and engines.

Wiper Seal
Description:
A wiper seal is used in hydraulic cylinders to prevent external contaminants from entering the hydraulic system.
Attributes:
The wiper seal cleans the hydraulic rod as it retracts and seals oil, eliminating weeping, or cosmetic leakage. This style of wiper seal is secured in place with a bearing mount, and contain a metal case for added strength.
Recommended Application:
This type of wiper seal is installed in the head of a hydraulic cylinder. The metal cased or "canned" wiper seal is pressed into the head.

Backup Ring
Description:
Backup Rings prevent seal extrusion in high pressure applications, and may be used to protect the life of overall sealing system from pressure surges.
Attributes:
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.
Applications:
Backup rings are used in high pressure static and dynamic sealing applications, such as hydraulic pumps, valves and engine systems.
