A device for sealing a hydraulic piston in a hydraulic cylinder includes a hydraulic piston defining a fluid side and an air side and having at least one sealing groove defining at least one sealing groove side wall and a sealing groove base. A lip seal is inserted into the sealing groove and comprises a sealing lip facing the fluid side and a seal back facing the air side. The hydraulic piston has means for improving sealing action of the lip seal comprising a shaping of the sealing groove on at least one of the at least one sealing groove side wall and/or the sealing groove base.
