Ask, and it shall be given...
Here are the parts for the grease nozzle/Zerk adapter. Notice the ball and spring to the left. These are the pieces to remove from the Zerk. Also note that the brass tube is preped for soldering.

Here is the assembled adapter. The shiny bit where the brass tube joins the Zerk is the soft solder sweated joint. I did not need to solder this particular adapter since the brass tube was a press fit into the Zerk, but I did it anyway.

And here is the adapter plugged into the end of the grease gun showing a little grease at the end.

I hope this helps you to visualize the assembled item.
