  • Patent number: 5588682
    Abstract: A system and method for electrically separating meters and pipes which carry combustible gases. The system includes at least one coupling (10). The coupling connects an electrically conductive conduit (12) to a gas meter (82) or other device. The coupling includes an electrically insulating layer (52) including a flange (61). A ring nut (74) engages a threaded portion (72) of a connecter to hold a resilient seal (14) in compressed relation between the flange and connector to provide a fluid tight connection. The coupling enables the flow of gas therethrough while electrically separating the conduit from the threaded connector. The system is easy to use, reliable, inexpensive and can be designed to be integral with a metal gas conducting conduit. Furthermore, the present invention provides improved performance, safety and long life due to the use of non-conductive material which impedes the flow of electricity along a gas line.
