Abstract
A filter element has a filter medium positioned between concentrically spaced cylindrical walls. A semiflexible, urethane ledge gasket has an annular seal portion that sealingly engages one end of the walls and filter medium and an edge of a generally circular retainer plate that closes one end of the filter element. An annular gripper surface extends inwardly from the seal portion and is spaced axially from the outer surface of the retainer plate so as to provide a finger gripping surface so that the filter element can be removed from its housing. An annular lip extends outwardly from the seal portion to engage an end of the housing.
