Product details
Weiss Industrial Thermowell | ESS3575SS | 7.5″ Length | 316 Stainless Steel
Product Description
The ESS3575SS is a precision-machined protective housing for industrial glass and bimetal thermometers. The “ESS” designation identifies this as a Stainless Steel Stepped Stem thermowell, which is designed to provide a faster thermal response than straight-shank models. The “75” indicates an overall length of 7.5 inches (190 mm), and the “SS” confirms it is manufactured from 316 Stainless Steel.
In the UAE’s demanding mechanical sector, 316 Stainless Steel is essential for systems handling treated water, saline environments, or aggressive chemicals. This 7.5-inch model is specifically sized to accommodate 6-inch (150 mm) stem thermometers, providing the necessary immersion depth to reach the core of the fluid stream while allowing the thermometer head to clear thick thermal insulation layers common in Dubai and Abu Dhabi projects.
Key Features
- High-Grade 316 Stainless Steel: Offers superior resistance to pitting and corrosion compared to standard 304 SS, making it ideal for the harsh environmental conditions of the Middle East.
- Stepped Stem Design: Features a reduced diameter at the tip to decrease thermal lag, ensuring the thermometer reacts quickly to temperature changes in the system.
- 5″ Total Length: Designed to perfectly house 6-inch stem thermometers, providing enough length for deep immersion in medium-to-large diameter pipelines.
- NPT Process Connection: Features standard threading for a leak-proof installation into pipe tees or tanks.
- Critical Protection: Allows for the removal and replacement of thermometers for calibration or repair without shutting down the system or draining the lines.

Frequently Asked Questions
- Q: Why use 316 Stainless Steel (SS) instead of Brass?
- A: Brass is suitable for general water service, but 316 SS is required for high-velocity chilled water, treated chemicals, or any application where longevity and chemical resistance are top priorities in the UAE.
- Q: Which thermometer fits this thermowell?
- A: This well is designed for any industrial thermometer with a 6-inch stem, such as the Weiss A9VU6 or 9VBM6 series.
- Q: Does this well have a lagging extension?
- A: This specific model is a standard well. If your pipe has exceptionally thick insulation (over 2 inches), you might require a model with an “extra-lagging” extension to ensure the thermometer dial is not buried.
