Product details
Weiss Thermowell | BSS3575BS | 304 Stainless Steel | 3-1/2″ Stem
Product Description
The BSS3575BS is specifically engineered for industrial thermometers with a 3-1/2″ stem. While brass wells are common for standard water lines, the 304 Stainless Steel construction of the BSS3575BS makes it the preferred choice for applications involving harsher fluids, higher temperatures, or where long-term durability is a priority in Dubai and Abu Dhabi’s industrial sectors.
This thermowell acts as a critical safety barrier, allowing for the removal or replacement of thermometers without depressurizing the system or risking fluid leaks. Its short 3-1/2″ design is ideal for installation in smaller diameter pipes or within manifold systems where space is limited but protection against the process media is vital.
Key Features
- 304 Stainless Steel Construction: Offers excellent resistance to corrosion and chemical attack, ensuring a long service life in industrial environments.
- High-Pressure Rating: Provides significantly higher mechanical strength compared to brass, making it suitable for high-velocity and higher-pressure process lines.
- Leak-Proof Maintenance: Facilitates instrument calibration or replacement without system downtime, maintaining continuous plant operation.
- Precision Fitment: Features a 3/4″ NPT process connection and the standard 1-1/4″ – 18 internal thread for universal industrial thermometer compatibility.
- Versatile Application: Suitable for a wide range of fluids, including chilled water, hot water, steam, and mild chemicals.

Frequently Asked Questions
- Q: When should I choose the BSS3575BS over the brass B3575BS?
- A: Choose the stainless steel model (BSS) if your system involves high-pressure steam, corrosive chemicals, or if the pipe velocity is high enough to cause mechanical fatigue in brass.
- Q: Is this model compatible with 316 Stainless Steel requirements?
- A: This model is 304 Stainless Steel. If your specifications strictly require 316SS for extreme marine or highly acidic environments, you should check for the “316SS” specific variant.
- Q: Will this fit a standard 9-inch industrial glass thermometer?
- A: Yes, as long as that 9-inch thermometer (case size) has a 3-1/2″ stem.
