Transition gasket

A mechanical pipe joint assembly configured to connect pipes of different diameters, the mechanical pipe joint assembly comprising:

• a first pipe that includes an annular pipe socket end that includes an annular cavity;
• an annular gland having a pipe bore disposed therethrough configured to receive a second pipe that has a different diameter than the first pipe and that engages the annular pipe socket end;
• wherein the annular gland further includes an annular tab located adjacent a periphery of the pipe bore;
• wherein the annular tab extends toward the annular cavity of the annular pipe socket end when the gland is directed toward the annular pipe socket end;
• a gasket that includes annular body having a bore disposed therethrough configured to receive the second pipe;
• wherein the gasket includes first and second sections wherein the first section includes a head and an abutment adjacent the head;
• wherein the second section includes a lip extension located adjacent the abutment of the first section and extending opposite the head of the first section;
• wherein the head of the first section of the gasket is configured to be circumscribed in the annular cavity of the annular pipe socket;
• wherein the annular tab of the gland is configured to set on top of the lip extension of the gasket;
• wherein the annular tab of the gland is engagable with the abutment of the gasket;
• wherein the lip extension of the gasket is compressed between the annular tab of the gland and the second pipe which creates a seal between the annular tab of the gland and the second pipe;
• and
• at least one fastener;
• wherein the at least one fastener engages the gland and the annular pipe socket end of the first pipe;
• wherein the at least one fastener draws the gland and the annular pipe socket end toward each other.

A gasket configured to seal a mechanical pipe joint having an annular pipe socket and a gland with a tab extending therefrom, the gasket comprising:

• an annular body having a bore disposed therethrough configured to receive the pipe;
• first and second sections wherein the first section includes an arcuate head and an abutment adjacent the arcuate head;
• wherein the arcuate head is arrow-head shaped with a point directed toward the annular pipe socket and opposite the abutment;
• wherein the second section includes a lip extension located adjacent the abutment of the first section and extending opposite the point of the arcuate head of the first section;
• wherein the lip extension of the second section is oriented substantially perpendicular to the abutment of the first section;
• wherein the arcuate head of the first section of the gasket is configured to be circumscribed in the annular pipe socket of the mechanical pipe joint and the lip extension of the second section is configured to fit underneath the tab of the gland while the tab of the gland is configured to apply a lateral force against the abutment of first section.
