Abstract: A funnel or drain back seal and systems, assemblies, components, kits, and methods thereof can comprise a body defining an opening that extends from a top of the body to a bottom of the body; a head portion that extends outward from the top of the body; and a flap or lip that extends outward from the bottom of the body. The opening can be adapted to pass draining oil from the top of the body to the bottom of the body for supply into an engine block.

Abstract: In one aspect, an unloaded annular flexible seal is provided to receive an end of a conduit and to provide a seal between the conduit and a flange of a machine. The seal has a base having an inner surface, an upper surface, an outer surface, and a lower surface, and a leg having an inner surface, an upper surface extending from the inner surface of the base, an outer surface extending from the lower surface of the base, and a lower surface. A surface area of the outer surface of the leg is greater than a surface area of the lower surface of the leg. In another aspect, the seal is included in a seal assembly that also includes an annular back-up member having an L-shaped cross section, including a back-up member base and a back-up member leg configured to sit in the groove of the flexible seal.
