Abstract
A sealing gasket that provides a seal between two members. The gasket includes a base at one end of the gasket and a gutter-forming surface at the opposite other end of the gasket. There is a pair of sides that join the one end and the opposite other end of the gasket. The sealing gasket is movable between a compressed condition wherein the gasket provides a seal between the two members and an uncompressed condition wherein the gasket does not provide a seal between the two members. When the gasket is in the compressed condition, the gutter-forming surface deforms to form a gutter along the one end of the gasket.

A sealing gasket that provides a seal between two members, the gasket comprising:
- a base at one end of the gasket and a gutter-forming surface at an opposite other end of the gasket, and the gasket having a minimum thickness along the gutter-forming surface;
- a pair of sides joining the one end and the opposite other end of the gasket;
- the sealing gasket being movable between a compressed condition wherein the gasket provides a seal between the two members and an uncompressed condition wherein the gasket does not provide a seal between the two members;
- and
- when the gasket is in the compressed condition, the gutter-forming surface deforms to form a gutter along the other end of the gasket, and wherein the gutter having a maximum depth greater than the minimum thickness of the sealing gasket along the gutter-forming surface.
A sealing gasket-retainer assembly that provides a seal between two members, the assembly comprising:
- a retainer affixed to one of the members;
- a gasket comprising a base at one end of the gasket, and the gasket attached at the base thereof to the retainer;
- the gasket further comprising an opposite other end;
- a pair of sides joining the one end and the opposite other end of the gasket;
- at least one retainer seal projecting from one of the side surfaces;
- the sealing gasket being movable between a compressed condition wherein the gasket provides a seal between the two members and an uncompressed condition wherein the gasket does not provide a seal between the two members;
- and
- when the gasket is in the compressed condition, the retainer seal deforms so as to contact the retainer and form a seal with the retainer.
