Trerice 3-4F2 Well

The Trerice 3-4F2 Well is a precision-engineered brass thermowell designed for heavy-duty HVAC industrial thermometer applications, specifically built to house 3.5-inch stem BX-Series industrial thermometers. As a critical pressure-containing component, this 3/4 inch NPT thermowell allows for the seamless removal or replacement of temperature sensors without depressurizing the system. This model serves as the direct Trerice T-2110-100 replacement, maintaining exact dimensional compatibility with legacy hardware.

Forged from high-grade brass, the 3-4F2 supports a maximum pressure rating of 300 PSI at 150°F and can withstand operating temperatures up to 600°F. With an insertion length (U-length) of 2.5 inches and a 0.44-inch bore, this well ensures optimal thermal response and protection against vortex shedding and high-velocity flow in liquid and steam pipelines. The 1/2-inch wrench allowance on the external hex provides a secure grip for leak-tight NPT process connection installation.

• Direct Retrofit Compatibility: Updated version for the T-2110-100, ensuring zero-modification fits for existing Trerice BX installations.
• System Integrity: Isolates the thermometer stem from corrosive media and pressurized flow, allowing for sensor maintenance while the system is live.
• Optimized Thermal Transfer: Precision-machined 0.44" bore minimizes air gaps when used with standard industrial thermometers.
• Durable Brass Construction: Provides excellent resistance to oxidation in water and non-corrosive process fluids.

Common Questions

Can I use the 3-4F2 with a different brand of industrial thermometer?
Yes, provided the thermometer has a 3.5-inch stem and a standard 1-1/4-18 UNEF coupling nut. However, it is specifically optimized for the Trerice BX9 series to ensure the sensor tip sits correctly in the flow stream.

Is this thermowell suitable for potable water applications?
The standard Trerice 3-4F2 is designed for industrial HVAC systems. For potable or drinking water systems requiring compliance with lead-free standards (NSF/ANSI 61), the 3-4F2PBF (Lead-Free Brass) version should be utilized.

How do I ensure the fastest temperature response time?
To maximize heat transfer between the process media and the thermometer sensor, it is recommended to apply a high-quality thermal heat transfer paste inside the well bore before inserting the instrument.
