In a fluid filter cartridge, and a method for manufacturing a fluid filter cartridge, a drain fitting is attached by a crimped joint to a housing of the filter cartridge. The drain fitting is loosely fitted into the housing, prior to forming the crimped joint. The drain fitting has an outer periphery thereof which includes a crimping recess therein and the housing includes a crimped portion thereof which is formed into the crimping recess of the drain fitting to form the crimped connection. The crimping recess further includes anti- rotation features in the form of raised ribs about which the crimped portion of the housing is formed for resisting rotation of the drain fitting with respect to the housing.
La présente invention concerne une cartouche de filtration de liquide et son procédé de fabrication. Un dispositif d~écoulement est fixé à un logement de la cartouche de filtration à l~aide d~un joint serti. Le dispositif d~écoulement est ajusté librement dans le logement, avant de former la liaison par sertissage. Le dispositif d~écoulement possède une périphérie externe qui renferme un évidement de sertissage et le logement contient une partie sertie qui constitue l~évidement de sertissage du dispositif d~écoulement afin d~obtenir une liaison par sertissage. En outre, l~évidement de sertissage présente des caractéristiques anti-rotation sous la forme de nervures verticales autour desquelles la partie sertie du logement est formée en vue de bloquer la rotation du dispositif d~écoulement par rapport au logement.
