Abstract
An annular air filter utilizes an end gasket which is snap fitted to a metal end cap. The gasket has a sealing lip with a radially extending, axially facing sealing face for sealing with a filter housing; and an annular, axially extending body portion. The annular, axially extending body portion has an axially extending, radially facing sealing surface for sealing with an air outlet pipe projecting into the housing. The gasket is made of foam rubber, rubber or polyurethane material and is optionally fixed on the air filter element with adhesive.
