A hollow port component (8) is attached to an aperture (10) of a cylinder (1) by providing the component (8) with an end portion (12) of reduced internal cross-section, passing the component through the aperture to a position in which its free end projects beyond the aperture and, whilst supporting the component against axial displacement in one direction, forcing a mandrel (15) through said end portion to expand the component against an adjacent surface of the cylinder and thereby lock the component axially in one direction. The component may be fixed directly to the cylinder wall or to an end closure plug component (5) secured to the cylinder.
