Internal Pipe Wrench

Internal pipe wrenches by Proto are used to remove broken threaded pipe ends, pipe plugs and fittings without damaging the pipe surface or thread. They are made from hardened steel and have a corrosion-resistant plating. These torque wrenches by Proto use an eccentric cam action to move the wrench against the walls of the pipe.

Working Mechanism

  • Adjust the wrench's jaws to fit around the fitting.
  • Position the wrench so that jaws are inside and the handle is outside the fitting.
  • Turn the handle to tighten the jaws around the fitting.
  • Once the jaws grip the fitting, use the handle to turn the fitting in the desired direction (clockwise to tighten it or counterclockwise to loosen it).
