  • Slip the plug onto the end of the wrench engaging pin "A" into the slot at the end of the wrench.
  • Turn the pin "A" into notch "B". This will hold the plug onto the end of the wrench.
  • Turn the wrench handle "F" clockwise with one hand while holding the wrench at "G" with the other until pin "D" on the wrench drops into the hole "E" in the Expander plug nut.
  • Insert the plug into the fitting or pipe.
  • Hold the wrench at "G" and turn the handle "F" clockwise to expand the plug.

To remove the wrench just push in on the wrench and turn clockwise enough to let pin "A" out of notch "B" and out the slot at the end of the wrench.


  • Slip notch in end of wrench over pin "A" and turn wrench right engaging pin "A" into notch at "C."
  • Hold the wrench at "G" with one hand and turn the wrench handle "F" counter clockwise to release the plug.
  • Remove the plug with the wrench.

Only hand tighten the plug to prevent damage to the wrench or plug. In expanding the plug, don't use any extra leverage on the wrench handle "F" as it is not necessary to tighten the plug any tighter than the ordinary man can pull on handle "F." Any extra leverage would tend to damage the wrench or the plug.
