1. An enhanced seal for installation between a first conduit comprising a first coupling and a second conduit comprising a second coupling, the enhanced seal comprising:
- an annular portion having an annular portion peripheral wall,the annular portion peripheral wall comprising an annular portion distal end, an annular portion proximal end, an annular portion interior surface circumscribing an annular portion central passageway extending from the annular portion distal end to the annular portion proximal end, an annular portion outer periphery, an annular portion length dimension extending from the annular portion distal end to the annular portion proximal end, an annular portion inner dimension perpendicular to the annular portion length dimension and extending between opposing sides of the annular portion interior surface, and an annular portion outer dimension perpendicular to the annular portion length dimension and extending between opposing sides of the annular portion outer periphery;
a cylindrical portion for insertion into the first coupling, the cylindrical portion having a cylindrical portion peripheral wall,the cylindrical portion peripheral wall comprising a cylindrical portion distal end, a cylindrical portion proximal end, a cylindrical portion interior surface circumscribing a cylindrical portion central passageway extending from the cylindrical portion distal end to the cylindrical portion proximal end, a cylindrical portion outer periphery, a cylindrical portion length dimension extending from the cylindrical portion distal end to the cylindrical portion proximal end, a cylindrical portion inner dimension perpendicular to the cylindrical portion length dimension and extending between opposing sides of the cylindrical portion interior surface, and a cylindrical portion outer dimension perpendicular to the cylindrical portion length dimension and extending between opposing sides of the cylindrical portion outer periphery;
the annular portion being either integrally formed with the cylindrical portion or being secured to the cylindrical portion such that the annular portion proximal end abuts the cylindrical portion proximal end, and the annular portion central passageway and the cylindrical portion central passageway are in fluid communication with one another;
the annular portion and the cylindrical portion comprise a resilient material having a Shore A durometer hardness greater than or equal to 70 and less than or equal 85;
the cylindrical portion length dimension being at least twice the annular portion length dimension;
the annular portion outer dimension being greater than the cylindrical portion outer dimension; and
two or more circumferentially spaced tabs extending radially outward from the annular portion.
