ABSTRACT:
A filter assembly comprises a filter (10) defining path for fluid passing to or from the filter (10). An adaptor (11) is connected to the filter (10) and provides a continuation of the path. The adaptor (11) is for mounting the filter (10) on a mounting plate (12) and carries one or more sealing rings (30, 37) that are engageable with the mounting plate (12). The adaptor (11) is made from a plastics material and one surface of the adaptor (11) is reinforced by contact with an annular reinforcing member (31) which may be of metal, particularly steel. This allows the flow path provided by the adaptor (11) to be maximized.
