Abstract
An annular fitting for connecting an immersion heater into a circulating fluid system which includes a groove cut across the threads on the inside of the fitting and a hole through the fitting wall in fluid communication with the groove. The groove and the hole permit a small quantity of fluid to bleed past the base of the heater to reduce the build up of bubbles around the base of the heater.
