A multi-part fluid filter housing having first and second parts and being arranged to contain a replaceable filter element includes complementary frusto-conical mating surfaces between the two parts. The two parts are held together by a screw threaded ring which is screwed onto the outer face of the first part and which includes an internal flange engaging an external flange on the second part. The second part is tapered to improve the flow characteristics of the housing and preferably includes a taper of between 1 and 2%. |
