Subject: Re: Pietenpol-List: cht thermocouple washer and copper spark plug washerannealingMike, You should not use a washer along with the ring type CHT Thermacouple. (it would shorten the plug) The ring type CHT should seal the same as the washer does. Just be careful and don't let it turn while tightening the plug. As far as annealing the thermocouple, I believe that would ruin the thermocouple.
