ABSTRACT:
A method and apparatus for sealing between an inner casing and an outer casing is provided. The method includes positioning a first sealing member in a leakage path defined between an inner casing and an outer casing such that leakage flow in a first direction activates the first sealing member, and positioning a second sealing member in the leakage path such that leakage flow in the first direction bypasses the second sealing member, and such that leakage flow in an opposite second direction activates the second sealing member. The apparatus includes a pair of circumferential grooves in a channel, a divider positioned in the channel that defines a leakage path, a first sealing member positioned to seal against a flow in the leakage path in a first direction, and a second sealing member positioned to seal against a flow in the leakage path in a second direction.
