Weiss Industrial Thermowell | EN6-75BS | 6″ Length | Brass | 2.5″ Lagging Extension
Product Description
The EN6-75BS is a specialized protective housing designed for 6-inch (150 mm) stem industrial thermometers. The “EN” designation identifies this as a Stepped Stem thermowell with a Lagging Extension.
In the UAE’s HVAC and district cooling sectors, pipes are often wrapped in thick thermal insulation (lagging) to prevent condensation. The EN6-75BS is engineered for these conditions; it features a total length of 6 inches, divided into a 2.5-inch insertion depth (U-dimension) and a 2.5-inch lagging extension. This design allows the thermometer sensor to reach the fluid stream in smaller pipes while the long neck extends past the insulation, making the dial easily readable for technicians in Dubai and Abu Dhabi mechanical rooms.
Key Features
- 5″ Lagging Extension: Specifically designed to clear thick pipe insulation, ensuring the thermometer is accessible and the dial is visible.
- Stepped Stem for Rapid Response: The reduced diameter at the sensing tip minimizes thermal mass, allowing the thermometer to react quickly to temperature changes.
- Premium Brass Construction: Provides excellent thermal conductivity and corrosion resistance for chilled water and non-aggressive fluid systems.
- Separable Socket Design: Enables the removal of the thermometer for calibration or replacement without shutting down the system or draining the fluid.
- Standard 3/4″ NPT Thread: The universal mounting size for mechanical piping, ensuring easy integration into standard pipe tees and fittings.

Frequently Asked Questions
- Q: When should I use EN6-75BS instead of ER6-75BS?
- A: Use the EN6 (this model) if you are installing into a smaller pipe with thick insulation. The ER6 has a longer 5-inch immersion but no lagging neck. The EN6 has a shorter 2.5-inch immersion but a long 2.5-inch neck to clear the lagging.
- Q: Which thermometer fits this well?
- A: It is designed for any industrial glass thermometer with a 6-inch stem, such as the Weiss 9VU6 or A9VU6 series.
- Q: Is this suitable for potable water?
- A: For drinking water systems in the UAE, you may be required to specify the Lead-Free (LF) version (EN6-75BSLF) to comply with local health regulations.
