Claim 14:
15. A connector for connecting a first pipe with a second pipe using power tongs having a die length, the connector comprising:
an elongate body extending between a first end and a second end;
a first connection portion with API interference fit threading on an inside surface of the body proximate the first end for connecting with the first pipe;
a second connection portion with API interference fit threading on the inside surface proximate the second end for connecting with a second pipe;
a recessed gripping surface defined on an outside surface of the body intermediate the first connection portion and the second connection portion, the recessed gripping surface extending along the outside surface for a gripping length at least as long as the die length, the recessed gripping surface adapted for gripping by the power tongs, wherein at least the portion of the body defining the recessed gripping surface comprises metal; and
a reinforced portion of the body extending along the body intermediate the first and second connection portions for resisting deformation of the body when a connection is made up with the connector, the reinforced portion comprising:
a first torque stop defined on the inside surface proximate the first connection portion for abutting a first nose of the first pipe when the first pipe is made up in the first connection portion; and
a second torque stop defined on the inside surface proximate the second connection portion for abutting a second nose of the second pipe when the second pipe is made up in the second connection portion,

wherein the body has a first outside diameter along at least one of the first connection portion and the second connection portion, and a second outside diameter along the recessed gripping surface, the first outside diameter being larger than the second outside diameter.
