Abstract: Fluid conduits for plumbing and other uses having integral end fittings are disclosed herein. A method of forming a fluid conduit in accordance with an embodiment of the disclosure includes providing a copper tube having a first inner diameter and a first wall thickness, and heat treating an end portion of the copper tube to a predetermined hardness. The method can further include increasing the wall thickness of the end portion from the first wall thickness to a second wall thickness, and increasing the inner diameter of the end portion from the first inner diameter to a second inner diameter. The method further includes forming a circular groove in an interior surface of the end portion and positioning a seal in the circular groove.

Abstract: Fluid conduits for plumbing and other uses having integral end fittings are disclosed herein. A fluid conduit configured in accordance with an embodiment of the disclosure includes a tube, such as a copper tube, having an end portion adjacent to a body portion. The body portion has a first wall thickness and the end portion has a second wall thickness that is greater than the first wall thickness. The fluid conduit also includes a seal positioned in an annular groove formed in an interior surface of the end portion. In this embodiment, the tube can be joined to another tube by at least partially compressing the end portion around a portion of the other tube.
