Abstract
A filter element of a liquid filter has a filter medium surrounding an element interior with a radially inner and a radially outer circumferential side as inflow side for raw fluid and outflow side for clean fluid, respectively. A sealing element arrangement of a sealing device is arranged at a filter medium end face. The sealing device seals a fluid connection between a liquid discharge line of a filter housing and the raw fluid side or clean fluid side of the filter element. The sealing element arrangement has radially inner and radially outer sealing elements extending circumferentially relative to the element axis. The radially outer and radially inner sealing elements are concave, viewed from a pressure-loadable side of the filter element. The radially outer sealing element has a radially outwardly or inwardly extending sealing lip; the radially inner sealing element has a radially inwardly or outwardly extending sealing lip.
