ABSTRACT:
The illustrated embodiment shows helical grooves of tapering cross section in the inner walls of the interfitting ends of the conduit sections for producing a rotation of the fluid as it enters and leaves the space between the annular terminal surface of one conduit end and the confronting interior ledge of the other. Because of the rotation any air bubbles are removed during filling of the conduit. For particularly vigorous rotation the annular terminal surface and/or interior ledge may be formed obliquely to the flow axis.
