A vent assembly comprises at least one vent 619 having a first end configured to face atmosphere, a second end opposite the first end, and a central portion provided between the first and second ends that includes a substantially conical portion having a varying diameter that is larger towards the second end. A substantially cylindrical portion is provided between the first end and the substantially conical portion, and a counter bore is positioned adjacent the first end. At least one of the first and second ends of the vent 619 provides a moulding seam 617a positioned out of the main air stream of the vent 619.
