ABSTRACT:
A universal gas valve finishing flange assembly is provided which is adapted to receive a plurality of different size gas valves. The finishing flange assembly comprises a flanged coupler comprising a pipe coupler having internal threads and a pair of ends. The internal threads are adapted to be received by a first gas shut-off valve with a valve stem leg having threads with a first diameter. The flanged coupler further includes a flange attached to one end of the coupler and is centered about an axis defined by the coupler. The flange further includes an orifice for receiving a gas valve key. A trim plate is also provided having a frontside and a backside and a hole there through to receive the pipe coupler. Also, the trim plate includes recess disposed in the frontside to receive the flange. Additionally, a reducer nipple is provided having outer threads and inner threads. The outer threads are correspondingly sized to be received by the internal threads of the pipe coupler, and the inner threads are adapted to be received by a second gas shut-off valve with a valve stem leg having threads with a second diameter.
