The disclosure described a pressurized fluid container comprising a fluid vessel, a sheath arrangement which may be fitted around the fluid vessel, and a mechanism for tightening the sheath around the fluid vessel. The disclosure also describes a filter assembly comprising a filter cartridge and sheath arrangement for supporting the filter cartridge against the pressure of a fluid flowing through the filter cartridge. The filter cartridge comprises an impervious shell, two end caps, and a porous filter unit. The shell has first and second ends, and the first and second end caps are respectively mounted at or near the first and second ends of the shell. At least one of the end caps may be slid along the shell and engages the shell to form a seal. The porous filter unit is positioned within the shell and has a first surface and a second surface. The filter cartridge further comprises an inlet structure containing an aperture which communicates with the first surface of the filter unit and an outlet structure containing an aperture which communicates with the second surface of the filter unit. The sheath arrangement includes a casing positioned within the shell and having first and second ends, first and second end restraints respectively mounted at or near the first and second ends of the casing, and a mechanism for fixing the first and second end restraints to the casing.
