Abstract : The present invention generally relates to sealing members and more particularly to a fluid sealing member that has both a dynamic seal and a static seal. The seals form a barrier between oil and ambient air. A hybrid sealing member has a sleeve with an inner surface dynamic seal and an outer surface static seal. The inner surface of the sleeve utilizes a plurality of quad ring seals having sides with undulations. The outer sleeve surfaces has a groove that holds an O-ring seal. Backup rings can be provided for both the quad rings and the O-rings to prevent slippage of the rings. (Author)
