FIELD: machine building.
SUBSTANCE: first, an initial annular projection of a triangular profile with the width of the base, which is calculated as per the relationship specified in the formula, is formed. Then, it is processed by plastic deformation using a processing tool by means of deformation from its top in the direction perpendicular to the stop surface of the part. The possibility of its elastic recovery is provided to the height equal to 10-60% of the height of initial annular sealing projection after the deforming force is released.
EFFECT: increasing tightness and operating life of a detachable connection.
