Is the pigtail terminated with a POL, or an ACME fitting... ACME fittings are colored to indicate different maximum flow rates. Black fittings are rated at 80,000 BTU/h, green fittings are 200,000 BTU/h rated, and red fittings are 400,000 BTU/h rated. POL fittings are available with or without an excess flow device.
