How to Connect an Impact Gun to a Compressor

Removing rusted bolts can be a frustrating and time-consuming task. Sometimes, no matter how much penetrating oil you use, you just don't have the leverage to remove the bolt. For those really stubborn bolts, an impact wrench can make all the difference. An impact wrench turns the high pressure air from your compressor into high torque for removing the most stubborn bolts. With the proper hose and fittings, connecting an impact wrench is quick and easy.

Things You'll Need

  • Impact wrench
  • Air compressor hose
  • Connect one end of a properly-rated air hose to the compressor by pulling back the release collar on the barrel connector attached to the end of the hose, sliding the connector over the air-outlet nipple on the compressor and releasing the collar.

  • Connect the other end of the hose to the impact wrench by pulling back the release collar on the barrel connector attached to the end of the hose, sliding the connector over the air inlet nipple on the wrench and releasing the collar.

  • Turn on the compressor and adjust the air pressure setting to the appropriate level for the tool that is connected to the compressor. Open the cutoff valve (if any) on the air outlet of the compressor.

  • Pull the trigger on the wrench briefly to check for proper operation.
