Technical Specifications
Back-up rings are protective and supporting elements with no sealing function. Made from extrusion-resistant materials, they typically feature a rectangular cross section and are installed in a groove with an elastomer O-Ring. Their tight fit in the housing prevents extrusion of the pressurized elastomer sealing element into the clearance or extrusion gap.
