Excellent tool to remove deeply recessed or stubborn aerators without damaging them.
Thrifco Plumbing 276-T Universal Aerator Removal Tool 4400276: This tool worked perfectly to remove a 24mm aerator from an American Standard bathroom faucet. The aerator was deeply recessed in the faucet body and it was impossible to put a wrench or pliers on the flats of the aerator. This tool was a godsend and did the trick.
