Resideo 121371M/U Copper NPT Well Assembly 3/4 NPT 3 inch insertion depth

Product Description

The RESIDEO 121371M/U copper well assembly is a metal thermowell designed for accurate temperature sensing in pressurized vessels. This 3/4 inch NPT well, with a 3 inch insertion depth, allows for precise temperature monitoring. It is specifically used with Aquastat controllers to securely hold the temperature sensing bulb within the controlled medium, preventing leakage and enabling easy maintenance.

• Allows efficient heat transfer while safeguarding the sensing bulb from direct contact with the controlled medium.
• Facilitates removal of the sensing bulb for testing or replacement without requiring system drainage.
• Designed for use with Aquastat controllers to secure the temperature sensing bulb and prevent leaks.
