Collet for Parker Aerometric 51 Front End (Tool 12827)

PARKER AEROMETRIC 51 FRONT END DISSASSEMBLY PISTOL GRIP COLLET.  Greatly simplifies the task of taking apart the shell/filling unit on an Aerometric Parker 51. An almost identical design to that used in the Parker factory, this tool incorporates a triple start thread just like that used on the joint between the filling unit and the front end of a fine thread Aerometric 51. THIS TOOL WON'T WORK ON THE LATER, COARSE THREAD AEROMETRICS. The thread configuration in the tool shown here consists of 3 parallel, non-intersecting, 16 TPI threads rather than one and it is very resource intensive to fabricate. The last photo shows all three threads starting in parallel inside the collet. Previous (non-Parker) suppliers of copies of this tool used a single, 48 TPI thread which does not match the Parker thread and can cause damage. This tool is true to form and will not mess up your threads if threads are lined-up before compression of the collet. A must for anyone working on a lot of 51s. This tool greatly simplified my life.
