This paper presents a method to calculate the distribution of the contact pressure between some packings and the stem, the change in the height of the piled-up packings and the axial-frictional force, at a given gland pressure for various combinations of asbestoid and graphitic packings. The analytical contact pressure between the graphitic packings and the stem is greater than that compared to using of asbestoid packings, because the value of the normal-to-axial pressure ratio of the graphitic packing is larger than that of the asbestoid one. The contact pressure on the packings tightened initially under the free-stem condition, and at the pushing and pulling of the stem, is larger than that tightened under a fixed-stem condition. The reaction pressure at the oposite side of the gland, the displacement of the packings and the axial-frictional force, under pulling and pushing of the stem, were experimentally obtained. These experimental observations agree fairly well with the analytical results.
