Product details
Weiss Bimetal Thermowell | BR6-75BS | 6″ Length | Brass
Product Description
The BR6-75BS is the industry-standard socket for 6-inch (150 mm) stem bimetal thermometers. The “BR” prefix identifies this as a Bimetal Thermowell with a Reduced Tip (External) design. The reduced tip features a tapered shank at the sensing end, which minimizes thermal mass and ensures a faster temperature response compared to straight-shank models.
The “6” indicates the nominal stem length it accommodates, and the “75” denotes the 3/4″ NPT process connection. In the UAE’s mechanical sector, this model is a staple for chilled water and HVAC systems. Unlike industrial glass thermometer wells (which use a large nut), the BR series features a 1/2″ NPT internal thread, which is the standard connection for bimetal dials in Dubai and Abu Dhabi.
Key Features
- Precision Thermal Response: The “Reduced Tip” design maximizes heat transfer to the bimetal sensing element for accurate, real-time readings.
- Premium Brass Construction: Provides excellent thermal conductivity and corrosion resistance in non-aggressive fluid systems like chilled water and domestic hot water.
- Separable Socket Design: Allows technicians to remove the thermometer for calibration or replacement while the system remains fully operational under pressure.
- Standard 3/4″ NPT Process Connection: The universal mounting size for mechanical piping, ensuring easy installation into standard pipe tees and fittings.
- 1/2″ NPT Instrument Thread: Specifically threaded to accept standard bimetal thermometers with a 1/2″ NPT fixed-thread connection.

Frequently Asked Questions
- Q: Which thermometer fits the BR6-75BS?
- A: It is designed for 3″ or 5″ dial bimetal thermometers with a 6-inch stem and a 1/2″ NPT connection, such as the Weiss 3BBM6 or 5BBM6 series.
- Q: What is the difference between BR6 and ER6?
- A: The BR6 is for bimetal thermometers (1/2″ NPT internal thread). The ER6 is for industrial glass thermometers (1-1/4″ – 18 UNEF internal thread). They are not interchangeable.
- Q: Can this be used in potable water?
- A: For drinking water systems in the UAE, verify if the project requires a Lead-Free (LF) certified version (BR6-75BSLF).
