Abstract

An air filter element having end caps molded of foam material, and in which one of the foam end caps also employs the foam material as a radial seal gasket.
Tubular inner and outer liners support a tubular filter element. The first ends are molded in a closed urethane end cap sealing one end of the filter element. The other end is molded to provide an open end cap in the form of an annular ring which encases the filter element and the liners, and provides a radial seal gasket. A
substantially rigid plastic ring has a base embedded in the open end cap annular ring, and an upstanding flange which carries the radial seal gasket. The ring closely fits within the inner liner, and the fit between the inner liner and ring provides a fluid restriction such that when the foamed urethane material forms on the annular flange, it carries up one side of the upstanding flange to form the ring, but is restrained from passing to the other side to leave an isolating gap between the other surface of the flange and the inner liner.
