(Boiler Reflex Sight Glass / Reflex Level Gauge Glass)
Product Overview
The Reflex Gauge Glass for boilers is essential for water level gauges. It shows clear and accurate liquid levels, even in tough conditions. Made from high-quality borosilicate glass, this reflex glass has a prismatic surface. This design creates a strong contrast between steam and water. This helps you read the water level accurately.
Reflex gauge glass outperforms traditional flat glass. It can withstand high pressure—up to 25 MPa—and thermal shock, reaching 300 °C. This makes it ideal for industrial boilers, where safety and reliability are crucial.

E-E-A-T Statement
We supply high-quality industrial sight glasses. This includes reflex gauge glass for boilers. We have more than 15 years of experience in power plants, chemical industries, and boiler manufacturing. This expertise helps us ensure our products meet strict safety and quality standards. Our processes are ISO 9001 certified.
Key Features and Benefits
High Pressure Resistance
Reflex gauge glass can handle boiler pressures up to 25 MPa (PN250). This ensures it remains durable and safe during high-pressure operations.
Excellent Thermal Shock Resistance
It can quickly change temperatures up to 300°C. This prevents cracks and failures during boiler startups and shutdowns.
Superior Visibility and Contrast
The prismatic surface reflects light in unique ways for steam and water. This creates a strong black and silver contrast. It helps measure water levels accurately.
Chemical and Corrosion Resistance
Made from borosilicate glass, it resists chemical corrosion. This includes damage from boiler water additives and steam condensate.
