Used in hydraulic applications, ATP anti-extrusion rings allow O-Rings to be used even with high pressures and high clearances. Anti-extrusion rings can be used individually or in pairs, in cases where O-Ring pressure is exerted in both directions. ATP anti-extrusion rings can be made in various materials and sizes depending on the application needs. As well as customised solutions, ATP provides a wide range of standard Anti-extrusion Rings for O-Rings.
