Apparatus for connecting wellsite tubing

An apparatus for connecting a first wellsite tube to a second wellsite tube, wherein each wellsite tube has an inner conduit and an outer conduit, comprising:

• a collar with internal threads at opposing ends, wherein said internal threads are configured to provide threaded engagement with the outer conduits of the first and second wellsite tubes;
• a coupling disposed inside said collar, wherein said coupling comprises a first end axially disposed from a second end;
• a first means configured to engage said first end of said coupling to the inner conduit of the first wellsite tube;
• a second means configured to engage said second end of said coupling to the inner conduit of the second wellsite tube;
• and
• a plurality of radially extending ribs disposed between said opposing ends of said collar, wherein said radially extending ribs support said coupling inside said collar.
