Abstract: A refillable filter-drier assembly for use in a refrigerant line. The assembly includes a shell or casing which houses a replaceable core having a central bore and which may be a filter, drier or strainer element or any combination thereof. Refrigerant enters the shell adjacent one end and occupies the space surrounding the core. The liquid passes inwardly through the core into the central bore and exits the casing from the end opposite from which it enters. The core is supported in spaced relationship with respect to the casing interior by an annular cage on the outlet end of the core and by an end closure cage on its opposite end. Both the annular cage and the end closure cage have resilient fingers which grip the core adjacent its opposite ends. Both the annular cage and the end closure cage also have pluralities of laterally extending lugs which support the core in its spaced relationship within the casing.
