Abstract
A method of connecting a plastic tube to a plastic hub is disclosed which includes preforming the tube by externally heating it in selected areas to cause outward bulging of the tube in those areas, applying an axial force on the tube to cause the bulges to compress axially while heated and molding the hub with the tube bulges in the mold.
