Tool for extracting annular carbon face seal from bore of equipment which seal is installed. Tool has extraction-tube for insertion into bore at entrance so, when extraction-tube is fully inserted into bore, multi-legged collet formed at distal-end of extraction-tube located within seal and proximal-end of extraction-tube accessible at entrance of bore. Tool has elongate-member extending along central passage of extraction-tube. Wedge element provided at distal-end of elongate-member located at mouth of collet. Proximal-end of elongate-member accessible at proximal-end of extraction-tube. Tool has support for reacting axial extraction force applied to extraction-tube to equipment. Tool has first-actuator at proximal-end of elongate-member. Tool configured so first-actuator causes wedge element to be pulled into collet, thereby expanding collet and causing to grip inner surface of seal. Tool has actuation second-actuator which operatively connects extraction-tube and support arrangement so actuation of second-actuator causes axial extraction force to extraction tube, whereby extraction force, reacted to equipment, extracts seal from bore when seal is gripped by collet.
