Abstract
An elongate mesh pack for filtering a fluid defines a mesh pack axial opening. The mesh pack comprises a filter medium for filtration of the fluid and has an end fitting securely fixed to the filter medium, the end fitting providing a first extremity of the mesh pack. The end fitting has an inner surface defining an end fitting opening through the end fitting, the end fitting opening being co-axial with the axial opening of the mesh pack. The end fitting comprises an annular recess encompassing the end fitting opening. A partition wall suitable to deform towards the recess under radial force is provided between the recess and the end fitting opening, the partition wall forming at least part of the inner surface.
