US Patent 7438327 Electrical connection assembly with unitary sealing and compression ring

An electrical connection assembly for securing electrical metal conduit to a junction box or the like, having a connection body with an inlet end portion for receiving a conduit wherein the inlet end includes a first portion sized to snugly receive an end portion of a conduit and a second portion having an internal surface that diverges outwardly toward the opening of the inlet end portion. A unitary sealing and compression ring is fitted onto the end portion of a conduit, and is positioned thereon so that the sealing ring portion of the unitary ring is received within the inlet end portion. A fastening nut secures the conduit to the inlet portion by causing the sealing ring portion to form a water or fluid tight seal between the connector body and the associated conduit and forming a mechanically sound connection between the connector body and the conduit. The unitary sealing and compression ring formed of metal insures positive electrical grounding of the assembled connection.
