The pistons are ring shaped with cup-shaped sealing surfaces extending towards a hydraulic supply port for sealing by hydraulic fluid. Spacers are provided between the pistons for preventing damage to the piston seals. First and second abutments are provided adjacent one end of the seal packer with a metal seal ring between the abutments and coacting wedge surfaces are provided on the metal seal and each of the abutments for sealing against both abutments and wedging the seal inward for sealing. Metal static seals are provided in the packer which are compressed by threads for providing high temperature seals.
