Patent ID: 8465654

Claim:
An elongate mesh pack for filtering a fluid, comprising: an elongated cylindrical mesh filter medium for filtration of the fluid, an end of which defines an axial opening; and an end fitting being securely fixed to the filter medium, providing a first extremity of the mesh pack, and having an inner surface defining an end fitting opening through the end fitting, said end fitting opening being co-axial with the axial opening of the mesh pack, the end fitting comprising an annular recess encompassing the end fitting opening, wherein an axially extending partition wall made of a material capable of deforming towards the recess under radial force, is provided between the recess and the end fitting opening, the partition wall defining at least part of the inner surface; wherein said partition wall deforms against a beveled extremity outer surface of a core tube when such a core tube is slidably moved into said axial opening of the elongate mesh pack, thereby fluidically sealing the end fitting to the core tube.
