Hydrolevel EL1214-P Standard Ceramic Probe with Long Nut 3/4" NPT

The Hydrolevel EL1214-P is a standard ceramic probe specifically designed for low water cut-off (LWCO) systems on steam and hot water boilers. This replacement probe features a long mounting nut (1-1/16") that accommodates thicker boiler jackets, making it ideal for installations where standard probes may not provide sufficient thread engagement.

Key Specifications:

• 3/4" NPT threaded connection for secure installation
• 2-7/8" inside dimension (ID) for proper water level sensing
• Standard ceramic construction for reliable conductivity sensing
• Long nut design (1-1/16") for thicker boiler jacket applications
• Compatible with Hydrolevel Safgard 24, 170, 400, 450, 500, 550, 600, 650, 700, and 750 Series controls
• Also compatible with CycleGard CG400 and CG450 Series controls

How It Works:

The ceramic probe uses water as a conductor to complete an electrical circuit between the probe and the boiler shell. When water levels drop below the probe, the circuit breaks and the low water cut-off control shuts down the burner to prevent dangerous dry-fire conditions. This simple yet effective design provides critical boiler protection with no moving parts to wear out or stick.

Replacement Part Information:

This probe replaces Hydrolevel part numbers EL1214-P and 45-226. The long nut version is essential for boilers with thicker insulation jackets or mounting configurations that require additional thread engagement compared to standard probe designs.
