1. An oxygen probe for a furnace, the oxygen probe including:
an elongate outer conductor;
an inner conductor within the outer conductor;
an oxygen sensor in electrical connection with the outer conductor and the inner conductor; and
a seal arrangement configured for receiving the inner conductor and for maintaining a seal to a reference chamber during movement of the inner conductor and the outer conductor owing to heat from the furnace;
wherein the seal arrangement includes an elongate, tubular seal formed from one of an elastomer and a synthetic rubber copolymer, the elongate, tubular seal being including a head from which a tail extends, the tail disposed about and extending along the inner conductor and into a sensor chamber.
