Abstract
An air filter element includes a media pack formed by inner and outer tubular liners and by a sleeve of filter media located between the liners. Moldable potting compound (e.g., Plastisol) is located at each end of the media pack to hold the liners and the filter media in assembled relation. A separately formed sealing gasket molded of Nitrile rubber is joined to one end of the media pack by a ring of the Plastisol, which encapsulates part of the sealing gasket. When the filter element is installed in a housing, the sealing gasket resiliently engages a sleeve and establishes a radial seal between the filter element and the sleeve. The end of the media pack opposite the sealing gasket is closed by a cap molded of the Plastisol and reinforced by a plate made of metal or stiff plastic.
