Mechanical joint gasket with protrusions

A gasket adapted to be a part of a mechanical joint, the gasket comprising:

• a ring-shaped body forming an opening, wherein the opening extends between a first end of the ring-shaped body and an opposing second end of the ring-shaped body;
• wherein the ring-shaped body has an inner surface adapted to engage a pipe;
• wherein the ring-shaped body has an outer surface that opposes the inner surface;
• wherein a first inner protrusion and a second inner protrusion are each formed on the body by the inner surface and extend toward a center of the opening;
• wherein the first inner protrusion is axially spaced from the first end;
• wherein the first inner protrusion is axially spaced from the second end;
• wherein the second inner protrusion is axially spaced from the first end;
• wherein the second inner protrusion is axially spaced from the second end;
• wherein the first inner protrusion defines a first inner peak;
• wherein the second inner protrusion defines a second inner peak;
• wherein the inner surface defines a first portion thereof between the first end and the first inner protrusion;
• wherein the first portion of the inner surface is continuously cylindrical, between the first end and the first inner protrusion, so that the first portion of the inner surface is devoid of any other inner protrusion between the first end and the first inner protrusion;
• wherein the inner surface defines a second portion thereof between the first inner protrusion and the second inner protrusion;
• wherein the second portion of the inner surface is continuously cylindrical, between the first inner protrusion and the second inner protrusion, so that the second portion of the inner surface is devoid of any other inner protrusion between the first inner protrusion and the second inner protrusion;
• wherein a dimension A is defined between the first inner peak and the first end;
• wherein a dimension B is defined between the first inner peak and the second inner peak;
• wherein a first outer protrusion and a second outer protrusion are formed on the body by the outer surface and extend away from the opening;
• wherein the first outer protrusion defines a first outer peak;
• wherein the second outer protrusion defines a second outer peak;
• wherein each of the first outer protrusion and the second outer protrusion is located axially and entirely between an end of the first inner protrusion and an end of the second inner protrusion;
• wherein the outer surface defines a portion thereof between the first outer protrusion and the second outer protrusion;
• wherein the portion of the outer surface is continuously frusto-conical, between the first outer protrusion and the second outer protrusion, so that the outer surface is devoid of any other outer protrusion between the first outer protrusion and the second outer protrusion;
• wherein a dimension H is defined between the first outer peak and the second outer peak;
• wherein a portion of the outer surface is angled relative to the inner surface;
• wherein the angled portion of the outer surface defines an angle J relative to the inner surface;
• wherein the first outer protrusion and the second outer protrusion are located within the angled portion of the outer surface;
• wherein the second outer protrusion is spaced from an end of the angled portion;
• wherein a dimension I is defined between the second outer peak and the end of the angled portion;
• wherein the dimension A ranges from 0.30 inches to 0.40 inches;
• wherein the dimension B ranges from 0.40 inches to 0.725 inches;
• wherein each of the first outer protrusion and the second outer protrusion is V-shaped thereby forming the first outer peak and the second outer peak, respectively;
• wherein each of the first outer peak and the second outer peak defines a height and each of the heights defines a dimension G;
• wherein each of the dimensions G ranges from 0.06 inches to 0.08 inches;
• wherein the dimension H ranges from 0.30 inches to 0.35 inches;
• wherein the dimension I ranges from 0.20 inches to 0.30 inches;
• wherein the angle J ranges from 15 degrees to 25 degrees;
• wherein each of the first inner protrusion and the second inner protrusion is V-shaped thereby forming the first inner peak and the second inner peak, respectively;
• wherein the V-shape of each of the first inner peak and the second inner peak forms an angle N;
• wherein each of the angles N ranges from 90 degrees to 110 degrees;
• wherein each of the first inner peak and the second inner peak defines a height and each of the heights defines a dimension M;
• and
• wherein each of the dimensions M ranges from 0.08 inches to 0.10 inches.
