Abstract
The invention relates to a hydraulic tool mount having a bore into which a sealing piston is inserted, wherein the sealing piston comprises a pin, a seal and a head which are arranged one behind the other in an axial direction (A) and thus form a stack, wherein the seal comprises a circumferential sealing lip for abutment and sealing against an inner wall of the bore in order to achieve a first sealing effect, and the bore comprises a sealing seat which, when the sealing piston is inserted, forms a stop for the head in axial direction (A), so that, in an end position of the sealing piston, the head abuts the sealing seat and thereby closes the bore in order to achieve a second sealing effect. The invention further relates to a corresponding sealing piston.
