Abstract
The invention relates to a piston-cylinder arrangement, especially a shock absorber piston, comprising a piston body fitted with a peripheral web protruding from the peripheral surface in a section adjacent to the end of the piston to which support webs are attached, said web extending parallel and spaced in relation to each other in longitudinal direction towards the other end of the piston. Two adjacent support webs limit a groove-shaped recess, said webs being open on the ends opposite the peripheral web in longitudinal direction. The piston also comprises a collar-shaped sealing element made of thermoformable plastic material that is formed on the piston body in such a way that only part of the height of both the peripheral web and the support webs is formed in the material of the collar-shaped sealing element.
