The present invention provides improved casing filling and circulating apparatus for running a casing string into a well bore using a drilling rig casing elevator and related equipment. The casing filling and circulating apparatus includes a flow passage therethrough and a check valve disposed within the flow passage for preventing spillage and for preventing fluid back-flow through the apparatus when the casing string is being lowered into a well bore. Additionally, the filling and circulating apparatus includes a pressure relief seal means which relieves pressure from the casing prior to when the filling and circulating apparatus is disconnected therefrom by back-flow through the apparatus thereby preventing spillage of fluid.
