1. A shunt closure with a compensator piston, the shunt closure comprising:
a compensator piston disposed between an oil chamber and a piston chamber and configured to translate towards the piston chamber to allow for an increase in the volume of the oil chamber;
a piston coupling connected to the compensator piston; wherein a portion of the piston coupling is configured to translate into the piston chamber upon translation of the compensator piston;
the piston chamber configured to house a portion of the piston coupling;
the oil chamber configured to house an oil; wherein thermal expansion of the oil applies pressure to the compensator piston; and
a shunt isolation sleeve coupled to and adjacent to the piston chamber.
