Prosthetic socket sealing system

A prosthetic system, comprising a prosthetic liner, comprising:

• a liner body having an open proximal end, and a closed distal end along a liner body axis;
• an attachment pin extending from the distal end of the liner body;
• and
• a sealing system including a first seal component arranged to form a seal around the attachment pin and seal against an interior surface of a prosthetic socket, the first seal component including a base surrounding the attachment pin and a sealing portion, the base defines a neck extending from a central portion of the base and directed distally along the liner body axis, the neck forming an opening therethrough through which the attachment pin extends, the sealing portion forming a wall segment extending circumferentially about the attachment pin;
• wherein the wall segment has an outer wall forming an outer peripheral portion of the wall segment and directed distally from a connection point with an inner wall of the wall segment toward the liner body axis with a diameter decreasing distally, and the wall segment defines the inner wall with a conical configuration with a decreasing diameter extending toward its distal end about the liner body axis, the outer wall and the inner wall securing to one another at a maximum diameter of the inner wall and at a proximally-most location of the inner wall at the connection point, the outer wall and the inner wall are arranged at different angles relative to one another such that a variable clearance is defined between the inner wall and the outer wall, the variable clearance increasing in the distal direction relative to the liner body axis.
