..375" or 3/8" Wayne & Marilyn Gorham
1/2 copper pipe size... 5/8OD.
My old caliper measures an OD of 3/8" on the stem of the Dial Thermometer that fits inside the thermowell. I might assume the ID of the Thermowell would be slightly large by a thou or two. Best regards ... Wes Kobelka
Yes, a brass thermowell is included to allow the thermometer to be removed without draining the system .
