A housing (20) for use in high-pressure fluid applications, comprising a first passage (100) defining a first axis (P1) and a second passage (200) defining a second axis (P2), wherein the first and second passages (100, 200) intersect at an opening defined by an intersection (22) at one end of the second passage (200). When sectioned on a plane normal to the second axis (P2) and not intersecting the first passage (100), the intersection (22) defines an ellipse (E) in the plane and centred on the second axis (P2), the ellipse having a major axis equal in length to the width (D2) of the intersection and a minor axis equal in length to the height (D1) of the intersection. A wall (212) of the intersection (22) describes a curve (218) in the plane, the curve (218) passing through the points (250, 252) where the major and minor axes of the ellipse (E) meet the perimeter of the ellipse (E), and through points (256) which lie outside the ellipse (E) and which are offset from the ellipse (E) by an offset distance (K).
