234-4581 Bucket Cylinder Head Support Ring

Description

Backup rings can prevent seal extrusion in high-pressure applications and can also be used to protect the life of the overall sealing system under sudden pressure changes.

Features

Cat® backup rings are designed around the characteristics of the elastomeric seal and mating components and contribute greatly to the life and performance of sealing systems in high-pressure applications.

Backup ring dimensions strictly adhere to tight tolerances, ensuring they properly bridge the seal groove and the mating surfaces. Materials are selected based on their pressure resistance and wear resistance.

Backup rings can be closed rings or split rings. Split rings are used to ensure ease of installation.

Cat sealing systems prevent leaks and contamination of more expensive parts. Protect your investment with Genuine Cat seals.

Applications

Backup rings are used in high-pressure static and dynamic sealing applications, for example, hydraulic pumps, valves, and engine systems.
