Abstract:
A method for combining a connection fitting (1) with an opposing surface, comprising the step of rotationally attaching the fitting (1) to the opposing surface, wherein the rotational attachment step comprises screwing the fitting (1) into the opposing surface by threads (3) on an outer surface of a fitting body (2), wherein said connection fitting (1) is formed by at least one seal (4, 4a), wherein the seal (4, 4a) is ring-shaped and lies in a ring groove (6) extending around a peripheral area of the fitting body (2), the seal (4, 4a) being flexible in an area of the ring groove (6) in an axial direction, wherein a radial depth of the ring groove (6) is approximately equal to or smaller than a radial overhang of the seal (4) in its non-deformed state relative to an outer diameter of the threads (3), the seal being manufactured together with a fitting body (2, 8) in an injection molding process thereby forming a multi-component plastic part in which the fitting body (2, 8) is made of a hard plastic component and the seal (4, 4a) is made of a soft plastic component, said hard and soft plastic components being of the kind that do not adhere to one another, and in which the seal (4, 4a) is secured in an axial direction on the fitting body (2) in a form-fit manner, wherein during the rotational attachment step the seal is rotatable relative to the fitting body (2).
