Back-Up Rings

Back-Up rings are specialized sealing components that provide additional support and protection to primary seals, such as O-rings, in high-pressure or high-temperature applications. Made from materials with high extrusion resistance, they prevent primary seals from being forced into the extrusion gap, maintaining seal integrity and extending service life. Commonly used in hydraulic and pneumatic systems, the selection of appropriate back-Up ring material and design is crucial for optimal sealing performance and reliability.
