Abstract
An aviation filter including an injection molded plastic ring that is formed with only a slight clearance relative to the outer diameter of the cylindrical metal filter. The ring includes an inner circumferential lip that snaps into a recess formed in a rolled seam on an end of the filter, and secured via an adhesive. The ring includes holes that receive a wire connected to corresponding tie downs formed on the mount. A method of manufacturing an aviation filter includes the steps of snapping the plastic lock ring into place on the filter, and using an adhesive to hold the ring in place against rotation.
