Abstract: Filter and seal for use therein. In a filter having a mesh basket and a fabric liner contained therein for functioning as a filter medium, there is provided an elastomeric rim for engaging and holding the free edge of the liner. A filter tank and cover are arranged for holding the basket in operating position and for receiving said elastomeric rim between the tank and cover where it acts both to hold the liner similarly in operating position and also as a seal therebetween. Said seal thus comprises a multipurpose component in that it provides a fluid seal between the inside of the housing and the atmosphere, retains the rim of the fabric filter liner and supports same, seals the filtered liquid from the unfiltered liquid and insures that the fabric liner is centered in the mesh basket.
