Seal means are circumferentially extending exteriorly around the mandrel and are urgable into sealing relation with the casing to prevent fluid communication thereacross, the seal means comprising at least one section of transversely compressible seamless, knitted elements generally defined by a continuous series of interlocking ductile metal-containing loop members.
