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.
L'invention concerne un anneau d'étanchéité à tube central destiné à être utilisé dans un ensemble filtre à double flux, qui comporte des surfaces annulaires fournissant un soutien supplémentaire aux éléments de filtre situés entre les surfaces en question et une bride d'étanchéité. Un congé est incorporé à chaque surface annulaire, s'étendant du corps de l'anneau vers la surface annulaire. Chaque congé est placé de manière à faciliter l'installation des anneaux dans leurs éléments de filtre respectifs. Chaque surface annulaire se verrouille sur l'élément de filtre correspondant, aux fins de préassemblage sur l'anneau, avant l'installation dans le boîtier de filtre. Cet anneau amélioré offre une stabilité accrue qui permet à l'axe des éléments de filtre d'être maintenu par rapport à l'axe du boîtier de filtre durant l'assemblage de l'ensemble filtre à double flux, réduisant ainsi les défauts d'assemblage.
