Abstract: A sealing element for a high-pressure connection, including a first portion and a second portion. The first portion is configured to dispose the sealing element in a clearance. A first side of the first portion is disposed so as to be substantially orthogonal to a second side of the second portion. The second portion has a third side, and the second portion is configured to press the third side onto a gap to be sealed when an increased ambient pressure acts on the second side.

Abstract: A sealing element for introduction into a cutout with a lubricant or without a lubricant, where the sealing element has a longitudinal extent direction. A sealing cross section of the sealing element is arranged substantially orthogonal to the longitudinal extent direction, where the sealing cross section includes a stabilizing surface. The stabilizing surface is configured to retain the sealing element in the cutout and/or to secure the sealing element in the cutout against tilting, where the sealing cross section further includes a retaining surface. The retaining surface including at least one securing element which projects from the stabilizing surface, where the retaining surface is configured to secure the sealing element against sliding out of the cutout by the securing element.
