    • 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.
    • 过滤元件具有位于同心间隔的圆柱形壁之间的过滤介质。 半柔性聚氨酯凸缘垫圈具有密封地接合壁的一端和过滤介质的环形密封部分和封闭过滤器元件的一端的大致圆形的保持板的边缘。 环形夹持器表面从密封部分向内延伸并且与保持板的外表面轴向间隔开,以便提供手指抓握表面,使得过滤元件能够从其外壳移除。 环形唇缘从密封部分向外延伸以接合壳体的端部。
