A method of forming a resilient seal, comprising the steps of: providing a cylindrical work piece defining a rib circumferentially protruding from an outer surface about a longitudinal axis of the work piece; providing a mold, said mold defining: a cylindrical receiving cavity configured to receive the cylindrical work piece, an annular seal cavity circumferentially extending about the longitudinal axis of the work piece and in communication with the cylindrical receiving cavity, and a port in communication with the seal cavity, wherein the mold is a one piece unitary mold and wherein the work piece is inserted into the receiving cavity through an opening defined by the receiving cavity; inserting the work piece within the receiving cavity such that the rib is circumferentially in intimate contact with an inner surface of the receiving cavity, wherein the rib is at least partially deformed as the work piece is inserted within the receiving cavity, wherein an outer surface of the work piece defines an annular work piece cavity circumferentially extending about the longitudinal axis, and wherein the work piece cavity is in communication with the seal cavity when the work piece is inserted within the receiving cavity; introducing a curable resilient material into the port, thereby filling the second cavity with the resilient material; curing the resilient material; and removing the work piece from the mold. providing a cylindrical work piece defining a rib circumferentially protruding from an outer surface about a longitudinal axis of the work piece; providing a mold, said mold defining: a cylindrical receiving cavity configured to receive the cylindrical work piece, an annular seal cavity circumferentially extending about the longitudinal axis of the work piece and in communication with the cylindrical receiving cavity, and a port in communication with the seal cavity, wherein the mold is a one piece unitary mold and wherein the work piece is inserted into the receiving cavity through an opening defined by the receiving cavity; inserting the work piece within the receiving cavity such that the rib is circumferentially in intimate contact with an inner surface of the receiving cavity, wherein the rib is at least partially deformed as the work piece is inserted within the receiving cavity, wherein an outer surface of the work piece defines an annular work piece cavity circumferentially extending about the longitudinal axis, and wherein the work piece cavity is in communication with the seal cavity when the work piece is inserted within the receiving cavity; introducing a curable resilient material into the port, thereby filling the second cavity with the resilient material; curing the resilient material; and removing the work piece from the mold. a cylindrical receiving cavity configured to receive the cylindrical work piece, an annular seal cavity circumferentially extending about the longitudinal axis of the work piece and in communication with the cylindrical receiving cavity, and a port in communication with the seal cavity, wherein the mold is a one piece unitary mold and wherein the work piece is inserted into the receiving cavity through an opening defined by the receiving cavity; inserting the work piece within the receiving cavity such that the rib is circumferentially in intimate contact with an inner surface of the receiving cavity, wherein the rib is at least partially deformed as the work piece is inserted within the receiving cavity, wherein an outer surface of the work piece defines an annular work piece cavity circumferentially extending about the longitudinal axis, and wherein the work piece cavity is in communication with the seal cavity when the work piece is inserted within the receiving cavity; introducing a curable resilient material into the port, thereby filling the second cavity with the resilient material; curing the resilient material; and removing the work piece from the mold.
