O-RING BACKUP WASHERS - Provides supplemental support of O-Ring seals in specific applications. Not intended to be used without O-Rings.
HIGH PRESSURE APPLICATIONS - Ideal for use in high pressure applications, such as with hydraulic cylinders, high-pressure valves, and high pressure, heavy-stress hydraulic systems.
PREVENTS O-RING EXTRUSION - Buna-N 90 O-Ring Backup Washers prevent O-Rings from flowing into the sealing gap when subjected to high pressures.
FOR USE IN APPROVED SYSTEMS - O-Ring Backup Washers must only be used in specific applications that have been engineered for their use. Using them in non-approved systems could result in equipment failure.
