A disclosure is provided describing a filling and circulating tool and method of use. The filling and circulating tool comprises a tubular housing having a first fluid passage and a longitudinal axis, a movable seal coupled to an exterior of the housing, the seal adapted to substantially block a flow of fluid through the first fluid passage when the seal is in a closed position and to allow the flow of fluid when the seal is in an open position, and an actuating device coupled to the movable seal such that in response to insertion into the casing, the actuating device causes the movable seal to move from the closed position to the open position.
