1. 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 on an inside surface of the body proximate the first end having interference fit threading for connecting with the first pipe;
a second connection portion on the inside surface proximate the second end having interference fit threading for connecting with the second pipe;
a gripping surface extending along an outside surface of the body intermediate the first connection portion and the second connection portion for a gripping length at least as long as the die length, the gripping surface comprising a recessed gripping surface, 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 intermediate the first connection portion and the second connection portion for resisting deformation of the body when a connection is made up with the connector,
