Weiss Thermowell | EN675SS | Brass | 6″ Stem with Lag Extension

Product Description

The EN675SS is engineered for use with industrial thermometers and sensors featuring a 6″ stem. Manufactured from high-quality Brass, this model is optimized for thermal responsiveness in water-based applications.

The standout feature of the EN675SS is its Lagging Extension, which provides extra length between the process connection and the instrument head. This is essential in the Middle Eastern construction market, where thick insulation is used on chilled water pipes to prevent condensation and energy loss. By using the EN675SS, the thermometer dial remains visible and accessible outside the insulation layer without compromising the pipe’s thermal seal.

Key Features

• Lagging Extension: Designed to clear pipe insulation, ensuring the instrument is easily readable and serviceable.
• Optimized for 6″ Stems: Provides the correct insertion depth for standard 6-inch industrial glass thermometers.
• Brass Construction: Offers excellent heat transfer properties and natural resistance to scale in HVAC applications.
• Maintenance Friendly: Permits the removal of thermometers for calibration or replacement without shutting down the system.
• Universal Threads: Equipped with a standard 3/4″ NPT process connection and 1-1/4″ – 18 internal thread.

Frequently Asked Questions

• Q: Why is the lagging extension necessary for UAE projects?
  • A: Most chilled water pipes in the UAE require thick insulation. The lagging extension ensures the thermometer sits above the insulation, preventing “burying” the gauge.
• Q: Can this be used for oil or gas lines?
  • A: While brass is compatible with many oils, for high-pressure gas or corrosive chemicals, Stainless Steel models are often preferred for safety.
• Q: Is this model compatible with Weiss 9″ industrial thermometers?
  • A: Yes, specifically those with a 6″ stem (the 9″ refers to the scale/case size, while the stem must match the well).
