An improved center-tube sealing grommet for use in a dual-flow filter assembly has annular lands which provide additional support to the filter elements located between the lands and a sealing flange. A fillet is incorporated into each annular land, extending from the grommet body to the annular land. Each fillet is positioned in a manner so as to facilitate the installation of the grommet into its respective filter element. Each annular land locks onto its respective filter element, providing a more rigid assembly that allows the filter element to be preassembled to the grommet prior to their installation into the filter housing. The improved center-tube sealing grommet provides increased stability which allows the axis of the filter elements to be maintained to the axis of the filter housing during the assembly of the dual-flow filter assembly, thereby reducing assembly defects.
