Sanhua launches upgraded SYJ sight glass range for high-pressure refrigerants

Sanhua has announced the launch of its new SYJ sight glass series, engineered to meet the demands of high-pressure refrigerants. Designed for use in liquid lines of refrigeration systems, the SYJ models provide visual indication of refrigerant condition and moisture level, with enhanced features aimed at reliability and compatibility.

The upgraded SYJ series features a wide-angle, high-clarity sight glass for improved readability. A color indicator allows for precise monitoring of the refrigerant’s moisture content. The sight glasses are constructed with corrosion-resistant brass and equipped with low-creep PTFE seals to ensure long-term, leak-free operation.

The SYJ sight glass is typically installed after the filter drier in the liquid line, helping technicians observe the refrigerant’s phase (liquid or vapor) and detect the presence of moisture. According to Sanhua, the new models are compatible with a broader range of refrigerants and are designed to gradually replace the existing SYJ versions in the market.

This product line update reflects Sanhua’s continued focus on durability and performance in refrigeration components.
