Abstract
A piston rod seal includes a sealing disk provided with a reinforcement element, a guide mechanism, and a support piece which are adapted to be placed consecutively in a metal pipe or similar object functioning as a housing, and which are adapted to surround a piston rod when installed. To create a seal having relatively few components and a relatively small axial dimension, the reinforcement element is connected to the sealing disk and is constructed to function as a guide element for guiding the axial movement of the piston rod.
