ABSTRACT:
There is disclosed a sealing ring comprising an integral piece of resilient metal formed into three or more U-shaped annular convolutions and having outer legs which extend from the convoluted section in a direction essentially parallel to but leading slightly away from the convolutions. The outer legs have a sinuous configuration and terminate in convex portions which define a sealing line when the sealing ring is installed.
