Made from high-quality materials such as SUS304 and 316 stainless steel, these stainless steel thermocouples meet the stringent standards required by industries such as electronics, automotive, and medical that require temperature accuracy. They are primarily used to provide durable and secure connections between thermocouple heads and wires in industrial heating systems.
Key Features and Specifications
- Temperature Range
Designed to operate within a temperature range of 0-200°C, making them suitable for a variety of industrial applications.
- Materials
Material: Made of high-quality SS304 and SS316 stainless steel, it is highly corrosion-resistant and durable. In harsh environments, 316 stainless steel can enhance protection against chemicals and high temperatures, ensuring long-term reliability under harsh conditions.

- Customization Options
- Diameter: Standard size of 3mm, but can be customized to fit your unique needs.
- Length: The standard length is 50mm, but custom lengths are available to accommodate different installation requirements.
- Female Thread: Compatible with 1/2NPT and 3/8NPT threads, and these can be customized as per your specifications.
- Easy Installation
The fittings feature a hexagonal shape, allowing easy handling and installation using common tools. This design ensures that you can securely tighten the fitting without risk of damaging the connection, especially in critical temperature monitoring applications.
- Precision Machined
With precision machining, the compression fittings are designed to ensure a leak-free and tight connection. This reduces the risk of faulty readings or temperature inconsistencies, which are essential in industries requiring exact measurements.
Applications
SUWAIE's Stainless Steel Thermocouple Fittings are designed for a wide range of industries that require precise temperature monitoring and reliable sensor connections. These fittings provide secure, long-lasting connections that help maintain the integrity of your temperature control systems. Below are some of the key applications:
- Bimetal Thermowells
These fittings are commonly used in bimetal thermowells, which are designed to protect temperature sensors from high-pressure and corrosive environments. The stainless steel thermocouple fittings ensure a secure connection, maintaining the accuracy of temperature readings in demanding applications.
- RTD Thermowells
In RTD (Resistance Temperature Detector) thermowells, the fittings help in connecting the thermocouple sensor and transmitter, making them ideal for temperature measurement in liquid, gas, or solid media. The fittings' high corrosion resistance and thermal stability ensure the RTD system operates accurately in various industrial processes.
- Protection Tubes
Thermocouple protection tubes play a critical role in protecting the sensor components from mechanical damage and harsh environmental conditions. With our 316 stainless steel thermocouple fittings, the protection tube systems are tightly sealed, ensuring long-term performance and reliability.
