Product details
Weiss Thermowell | E3575BS | Brass | 3-1/2″ Stem
Product Description
The E3575BS is specifically designed for use with industrial glass thermometers featuring a 3-1/2″ stem. Crafted from high-grade Brass, it provides excellent thermal conductivity, ensuring fast and accurate temperature response for chilled water and hot water systems.
In the UAE’s district cooling and building management sectors, the E3575BS acts as a permanent pressure seal, allowing the thermometer to be removed for calibration or replacement without the need to drain the piping system. Its robust 3/4″ NPT process connection is a standard fit for most industrial manifolds and pipe fittings in the Middle East.
Key Features
- High Thermal Conductivity: Brass construction ensures rapid heat transfer for real-time temperature monitoring.
- System Integrity: Provides a permanent seal, protecting personnel and equipment from process fluids during instrument maintenance.
- Standardized Fitting: Features a 3/4″ NPT external thread and 1-1/4″ – 18 internal thread for universal industrial compatibility.
- Corrosion Resistant: Ideal for non-corrosive fluid applications such as HVAC, plumbing, and irrigation systems.
- Durable Protection: Shields thermometer stems from mechanical fatigue and high-velocity flow damage.

Frequently Asked Questions
- Q: Can this thermowell be used in sea water applications?
- A: For sea water or highly corrosive fluids, Stainless Steel (316SS) or Monel thermowells are recommended over brass to prevent dezincification.
- Q: Is it compatible with digital temperature probes?
- A: Yes, provided the probe has a matching 1-1/4″ – 18 swivel nut and the correct stem length.
- Q: Does it include a lagging extension?
- A: The E3575BS is a standard well; for insulated pipes, you may require a “Lagging Extension” model to clear the insulation thickness.
