Hydrolevel EL1150 Sensing Probe 328140-751 The internal NPT thread connectionsThe Hydrolevel EL1150 Sensing Probe (Part Number 45 210) is a critical component designed for 1150 Series Low Water Cut Off (LWCO) controls. Engineered for high temperature and high pressure residential or commercial boiler applications, this probe utilizes a 3 4" NPT threaded connection and features a precise 1 15 16" inside dimension (ID). This specific length is crucial for maintaining the 1 4" minimum clearance from the metal probe tip to the
