If you already have a natural gas grill, using a quick connect is an easy way to add a stir fry stove like EasyFlamer. The quick connect allows you to change to different stove (grill) easily. The quick connect comes in a socket and a plug. The socket goes to the natural gas supply and shut off automatically if the plug is not connected. The plug goes to the appliance. Both socket and plug accepts 3/8" male pipe threads. If you order an EasyFlamer natural gas stove along with this connector, we install the plug on the stove side for you. Our price is $29.98 plus shipping.
