About Back Up Ring:
A backup ring is a type of seal used in hydraulic and pneumatic
systems to prevent fluid or gas leakage. It is typically installed
as a secondary seal in conjunction with the primary seal to provide
an added layer of protection. In the event that the primary seal
fails, the backup ring takes over and prevents the fluid or gas
from leaking out of the system.
Backup rings are typically made from materials such as Teflon,
polyurethane, or rubber. They are designed to fit snugly against
the primary seal and provide an additional barrier to prevent
leakage. Backup rings are commonly used in high-pressure
applications where even a small amount of leakage can be
problematic.
In summary, a backup ring is an important component in hydraulic
and pneumatic systems that provides an added layer of protection
against fluid or gas leakage. It is typically installed as a
secondary seal in conjunction with the primary seal and is made
from materials such as Teflon, polyurethane, or rubber.
