Abstract

A filter cartridge having an endplate formed of polyurethane having a varying hardness is described. A first portion of the endplate is harder than a second portion of the endplate. The first portion of the endplate helps support the filter media of the filter element and maintain the shape of the filter element. The second, softer portion creates a seal between the filter element and a filter housing when the filter element is installed in the filter housing. The first portion and separate portions may be formed from different types of polyurethane or from the same type of polyurethane having a varying composition as a function of the radial distance of the endplate.
