325-3781 - 371.72mm Inner Diameter Backup Ring

Cat 371.72mm Inner Diameter Plastic Backup Ring used in Piston of Planetary Carrier

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.
