A sealing apparatus for engaging a tubular, comprising:

• a body;
• a sealing system disposed about the body;
• one or more extrusion rings disposed at each end of the sealing system;
• a first cone for supporting the one or more extrusion rings;
• a second cone expandable over the first cone;
• and
• a slip member disposed adjacent to the a cone at each end of the sealing system, whereby actuating the sealing apparatus expands the sealing system and causes the slip member to fold outward and engage the tubular.

A method of sealing a tubular, comprising:

• running a tool into the tubular, the tool comprising:
• a body;
• a sealing system disposed about the body;
• an extrusion ring disposed adjacent each end of the sealing system;
• a cone disposed adjacent each extrusion ring;
• and
• a slip member disposed adjacent each cone;
• applying a force to the slip member at one end of the tool;
• expanding the sealing system into contact with an area of the tubular;
• causing the extrusion ring to fold outward and plastically deform;
• and
• causing the slip member to engage the tubular, wherein the sealing member, extrusion ring, and the slip member are set in a predetermined sequence.
