TUBING END AND METHOD FOR FORMING |
摘要 |
The present invention comprises a tubing end fitting and a method of forming thereof wherein the fitting is formed out of the tubing itself. In a first step, the tubing end is compressed in a linear direction and shortened forming a first annular ridge extending around the tubing spaced from the end of the tube by a small tube portion. At the same time, the small tube portion diameter is reduced slightly. The small tube end portion is again compressed slightly in a linear direction initiating the formation of a second annular ridge spaced from the first annular ridge, while at the same time again slightly reducing the diameter of the remaining tubing end portion. In a third step the tubing end is again compressed in a linear direction completing the formation of the second annular ridge. In a fourth step the remaining tube end portion is flared outwardly forming an o-ring receiving groove between the second annular ridge and the tube end.
