A Backup Ring is a type of sealing component that is used in conjunction with an O-ring to prevent extrusion under high pressure and temperature conditions. It is made of a harder material than the O-ring, such as plastic, and is placed on the opposite side of the O-ring from the pressure source for secure sealing.Attributes:• Features a slit cut on the Backup Ring which helps equalize the pressure buildup on the primary sealing element • Ensures the proper sealing function for the Cylinder RodApplications:A Backup Ring acts as a barrier, distributing the load evenly across the sealing components and preventing the primary seal from extruding into the gaps between them.
