White-Rodgers F89-0063 Well

The White-Rodgers F89-0063 immersion well is a critical component for technicians installing or maintaining hydronic temperature controls in closed-loop systems. Designed for 3/4 inch NPT pipe threads, this well provides a robust protective housing that allows the sensing bulb to monitor liquid temperatures without direct fluid contact. This infrastructure is essential for hydronic heating systems and commercial boilers, as it enables the removal or replacement of the temperature control bulb without the need to drain the entire system tank. Engineering specifications confirm compatibility with thermowell applications requiring a standard shank length and precise thermal transfer. The F89-0063 is particularly suited for use with White-Rodgers 11B18, 11B05, 11B55, and 1131 series controls, ensuring a seamless interface between the thermal sensor and the system medium. By utilizing a high-quality immersion well, contractors maintain system integrity while securing accurate temperature readings for building automation and HVAC controls.

• System Isolation: Allows for total control bulb maintenance or replacement without draining the boiler or hydronic loop.
• Universal Compatibility: Specifically engineered for White-Rodgers 11B18, 11B05, and 11B55 series hydronic controls.
• Standardized Fit: Features a 3/4" NPT connection for standard piping infrastructure and universal interchangeable well designs.
• Durable Protection: Shields sensitive bulb capillary elements from corrosive fluids and high-pressure environments.
• Thermal Accuracy: High-conductivity housing ensures rapid temperature response for building control system monitoring.

What is the thread size for the F89-0063?
This model utilizes a 3/4 inch NPT pipe size for the well spud connection.

Can I remove the sensor while the system is pressurized?
Yes, because the immersion well acts as a physical barrier between the sensor bulb and the system fluid, the sensor can be withdrawn without leakage or pressure loss.

Which White-Rodgers controls fit this well?
It is primarily used with the 11B18, 11B05, 11B55, and 1131 series hydronic elements.
