Abstract: Embodiments of the present disclosure provide an apparatus and method for mounting an O-ring to a work piece. The apparatus comprises a guiding component comprising a frustum portion arranged coaxially with a groove formed on an end surface of the work piece for receiving the O-ring, a large end face of the frustum portion arranged adjacent to the end surface; and an operation component adapted to drive the guiding component to rotate back and forth about a central axis of the guiding component, wherein a diameter of the large end face is substantially same as an inner diameter of the O-ring to allow the O-ring surrounding and eccentric to the frustum portion to slide into the groove with a rotation of the guiding component.
