1. An apparatus comprising:
a prosthetic socket having an open proximal end configured for insertion of a residual limb, a distal end configured to reach across a distal end of the residual limb, a peripheral shoulder within the socket, a first interior periphery reaching from the shoulder to the distal end, and a second interior periphery reaching from the shoulder to the open proximal end, wherein the second interior periphery is enlarged relative to the first interior periphery to define a receiving section of the socket having a depth that is recessed outwardly from the first interior periphery to the second interior periphery;
a sealing sleeve received within the receiving section of the socket, the sealing sleeve having a distal end within the receiving section of the socket between the shoulder and the open proximal end of the socket; and
a ring-shaped inner brim received within the receiving section of the socket between the residual limb and the sealing sleeve, the inner brim having both a proximal end and a distal end within the receiving section of the socket between the shoulder and the open proximal end of the socket, and having a thickness less than the depth of the receiving section, whereby the inner brim is contained entirely within the receiving area of the socket and seals the sealing sleeve against the socket within the receiving section of the socket.
