FIELD: machine building.
SUBSTANCE: invention refers to threaded tube connection. An external tube connection is made between the part of a pin and part of a seat, ends of parts of which contain additional threaded parts adapted for engaging each other along the bigger part of their axial length. Threads are inclined in the same direction and at acute angle to lengthwise axis of the connection. Part of the seat runs at least to a stop lug having an upper part in form of a truncated cone; this part is located next to an additional recess for the stop lug in the part of the pin. The additional recess for the stop lug contains a conic receiving part of conic cross section for installation of the upper part in form of truncated cone with compaction. Also there is made a circular slot of an intermediary threaded part of the seat.
EFFECT: increased reliability of connection.
