Product details
Weiss Thermowell | BR675BS | Brass | 6″ Stem
Product Description
The BR675BS is a fundamental component for HVAC and industrial fluid systems across the UAE. Designed for thermometers with a 6″ stem, this brass well provides a robust barrier between the instrument and the process media. Its brass construction is highly valued in the Middle Eastern market for its exceptional thermal conductivity and reliable performance in water-based applications.
By installing the BR675BS, facility managers and technicians can replace or calibrate thermometers without the risk of system leaks or the need for a total system shutdown. This is particularly critical in large-scale residential and commercial developments in Dubai and Abu Dhabi, where maintaining continuous chilled water flow is essential.
Key Features
- Optimized Thermal Response: High-grade brass allows for rapid temperature conduction from the fluid to the sensing element.
- Standard 6″ Fitment: Specifically machined to accommodate industrial glass thermometers with a standard 6-inch stem.
- Leak-Free Maintenance: Acts as a permanent pressure seal, allowing instrument service while the system remains pressurized.
- Robust Process Connection: Features a heavy-duty 3/4″ NPT external thread for secure mounting into pipe tees or manifolds.
- Corrosion Resistance: Suitable for non-corrosive environments, including potable water, hot water heating, and chilled water loops.

Frequently Asked Questions
- Q: Does the BR675BS include a lagging extension for insulation?
- A: No, this is a standard-style well. If your pipes are heavily insulated, the EN675SS model (which includes a lagging extension) is recommended.
- Q: Can this well be used with digital sensors?
- A: Yes, as long as the digital probe has the corresponding 1-1/4″ – 18 connection and is sized for a 6″ insertion depth.
- Q: Is brass suitable for high-pressure steam?
- A: For high-pressure steam or high-velocity industrial applications, a Stainless Steel thermowell is generally preferred over brass for increased mechanical strength.
