Description
The Carrier 4662 is a precision-engineered 304 stainless steel thermowell designed to protect temperature sensors and probes in hydronic, HVAC, and light industrial piping systems. With a 1/2″ NPT threaded connection, a 2-1/2″ insertion length, and a .260″ stem diameter, this thermowell provides a secure, leak-free interface between your temperature-sensing element and the process fluid — allowing sensor removal and replacement without interrupting system operation.
Key Features
- 1/2″ NPT threaded process connection for easy installation into standard pipe fittings and tees
- 2-1/2″ insertion length ensures the sensing tip reaches the active flow zone for accurate temperature measurement
- .260″ stem diameter provides a slim profile while maintaining structural rigidity
- 304 stainless steel construction delivers excellent corrosion resistance in water, glycol, and mild chemical environments
- Protects temperature sensors from flow velocity, pressure, and chemical attack, extending sensor service life
- Allows sensor removal and replacement without draining or shutting down the system
