Th e extrusion behavior
of new sealing materials
 is determined, for example,
by using rectangular piston
seals or standard rings. When using this method extrusion occurs as a result of the specifi ed loadings and the radial gap behind the seal. It can be measured as a permanent plastic deformation resulting from the intrusion of the material into the radial gap under the applied load.
