Abstract:
1. A compression seal for co-axial pipes comprising: a sealing ring including a frustro-conical outside shape for engaging opposing cylindrical surfaces of said co-axial pipes, such that upon compression, said sealing ring is in mechanical communication with an outside diameter of an inner pipe, and in mechanical communication with an inside diameter of an outer pipe; and a spring ejector ring in contact with and separable from said sealing ring, said spring ejector ring including a frustro-conical outside shape of a diameter less than said sealing ring such that upon insertion and absent axial compression, said spring ejector ring forms a gap with said outside diameter of said inner pipe and a gap with said inside diameter of said outer pipe, and generates sufficient force to eject said sealing ring upon removal of a sealing axial compression force.
