A filter candle (100) as subject of the present invention comprises: an elongated mesh pack (200) for filtering a fluid, comprising an end fitting (206) securely fixed to a filter medium (205). Further, a hollow core tube (300) is provided having a fluid permeable wall, the core tube being positioned within the axial opening (203) of the mesh pack. The core tube has an end flange (340) fixed to the outer end surface (312), which end flange is suitable for engaging the end fitting on the mesh pack. A ring-shaped seal (500) is provided between and making contact with the outer end surface of the core tube, the end fitting and the end flange. The seal is a porous ring-shaped structure comprising a multitude of pores, which pores have an average pore size being equal or less than the filter rating of the filter medium. |
