PTUBW & PTUSW BULB TYPE IS PTU STYLE COPPER SENSING BULB WITH THERMOWELL. THE ISOLATION WELL, WHICH ISOLATES THE COPPER SENSING BULB FROM THE PROCESS FLUID, IS AVAILABLE IN EITHER BRASS OR 316L STAINLESS STEEL. SENSING BULB CAN BE REMOVED BY UNSCREWING UNION NUT. UNION HUB & ISOLATION WELL REMAIN IN PLACE WHICH ALLOWS THE REMOVAL OF THE SENSING BULB WITHOUT HAVING TO DRAIN THE TANK.
