10/F GONG

This 10mm Female Tool holds the 10mm Male Glass Joint.  Comes with a 10" SS Tube.

We cannot guarantee that the ground joint holder will run perfectly true.  The variable is the Stainless Steel Tubing.  We have no control over this. 

For best results , try running the ground joint holder within 2 inches behind the graphite head.

For a perfectly true running joint "guaranteed" , try the 12" Graphite ground joint holder
