Seal 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.
