The sleeve also has a downstream fluid outlet end region comprised of two or more lips which are opposed to each other and symmetrically arranged relative to the axis, wherein the lips extend a defined length along the axis, the defined length being within the range of about 1:1.5 to 1:9 times the diameter of the conduit.
