Abstract
Official abstract text for this publication.
A tube connection for connection to a tube includes: a body having a through hole with a central axis, a first end, a second end, and an internal thread arranged close to the first end and coaxial with the central axis. The internal thread has a constant pitch diameter. A maximum diameter of the internal thread increases in an axial direction from the first end towards the second end. A minimum diameter of the internal thread decreases in the axial direction from the first end towards the second end.
First claim
Opening claim text (preview).
1 . A tube connection for connection to a tube, comprising: a body having a through hole with a central axis, a first end, a second end, and an internal thread arranged close to the first end and coaxial with the central axis, wherein the internal thread has a constant pitch diameter, wherein a maximum diameter of the internal thread increases in an axial direction from the first end towards the second end, and wherein a minimum diameter of the internal thread decreases in the axial direction from the first end towards the second end. 2 . The tube connection according to claim 1 , wherein the internal thread starts at a distance from the first end, such that a cylindrical surface is provided in the through hole between the first end and the thread. 3 . The tube connection according to claim 2 , wherein a diameter of the cylindrical surface is equal to a pitch diameter. 4 . The tube connection according to claim 1 , wherein the maximum diameter and minimum diameter are equal at a start of the thread. 5 . The tube connection according to claim 1 , wherein the minimum diameter decreases at an angle of 1°-5°. 6 . The tube connection according to claim 1 , wherein the body comprises a hexagonal prism shape, and wherein an axis of the hexagonal prism shape is coaxial with the central axis.
