Abstract

A seal arrangement for a filter for fluid-tight sealing between a filter element and a filter head includes an annular elastic seal, a filter head sealing face and a filter element sealing face. The seal has a filter head side facing the filter head sealing face, a filter element side facing the filter element sealing face, an inner face running circumferentially on the inner side, and an outer face running circumferentially on the lateral side. The filter head side has a circumferential first recess between the inner and outer faces. The filter element side has a circumferential second recess between the inner and outer faces. The seal arrangement is configured in such a way that the seal, when subjected to a pressure from the inner face and/or from the outer face, is wedged in the direction of the acting force, between part faces of the sealing faces that narrow toward the middle.
