ABSTRACT:
A tube joint including a male end which has a rounded inner edge having its original surface finish and a female end which is expanded to receive the male end. The male end is formed by chamfering the end outer diameter and flaring the end inner diameter until the end inner diameter is substantially rounded. The female end is expanded so its inner diameter is only slightly greater than the outer diameter of the male end.
