ABSTRACT:
A gas service tee designed to facilitate tamper-proof termination of gas service to a residential or business location and/or removal of the gas meter without interruption of gas service. The gas service tee is characterized in a first preferred embodiment by a tee fitting located in the gas service line downstream from the gas meter and an adaptor having a tamper-proof adaptor stem mounted in the tee fitting, which adaptor stem can be adjusted to stop the flow of gas through the line. In a second preferred embodiment of the invention the adaptor stem is hollow and is provided with spaced stem openings and a stem grip may be provided for threadably rotating the stem inside an adaptor fitting located in the tee fitting. A tube fitting may also be provided on the stem or stem grip for receiving the hose of an auxiliary gas supply bottle and supplying gas to the residential or business location while the gas meter is being repaired or replaced.
