A floating seal portion is positioned within the retainer, with a spring positioned inward of an inner end of the floating seal portion, and biasing the floating seal portion outwardly. There is an inner bore of the retainer which is spaced from an outer periphery of the floating seal portion. One of the inner bore and the outer periphery presides with the plurality of radially located pins. The other of the inner bore and the outer periphery is formed with the plurality of recesses. The pins are received in the recesses, to prevent rotation of the floating seal portion within the retainer.
