Quick-connect coupling for thin-walled pipes

摘要

A quick-connect coupling is disclosed for thin-walled pipes which can accommodate pipes of the same internal diameter but of differing wall thickness, the coupling member being constructed to deform pipes of less than maximum wall thickness into a substantially elliptical condition in which the coupling is fully seated, bolting pads of the coupling being spaced from each other to induce deformation and seating of the pipes upon tightening of the coupling.
