Abstract
A tube coupling assembly includes first and second generally cylindrical coupling components each terminating in a radially outwardly extending flange surrounding a sealing end face. The coupling components are positioned in axial alignment and an improved nut assembly is provided for selectively driving the sealing end faces toward one another. The nut assembly comprises a sleeve-like main body positioned in surrounding relationship to the first and second coupling components. A nut member is threadedly connected with a first end of the main body and engages with the radially outwardly extending flange on the first coupling component on the side opposite its sealing face. A split-ring connector comprising cooperating half-ring members is positioned in surrounding relationship to the second end of the main body and releasably connected thereto. The half-ring members include radially inwardly extending flanges engaged with the radially outwardly extending flange on the second coupling component on the side opposite its sealing face.
