133-3715: 35.53mm Inner Diameter 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: • Steel backup ring • Thickness: 0.91 mm • 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. Application: Backup rings are used in high pressure static and dynamic sealing applications, such as hydraulic pumps, valves and engine systems.
