Flow Sight Glass in Stainless Steel – Quality and Control at an Unbeatable Price

Our sight glass Type GD100 is versatile and meets high requirements for visual inspection and safety. This stainless steel sight glass is available with flange or socket connection and integrates seamlessly into existing systems. The body made of stainless steel (1.4408/CF8M) offers highest corrosion resistance and durability. Equipped with a PTFE gasket and soda-lime tempered glass (DIN 8902), it is designed for operation up to 130°C (briefly 160°C) and operating pressures up to 16 bar.

This flow sight glass with soda-lime glass DIN 8902 is an economical and reliable choice for use in non-aggressive applications in the low to medium temperature range. Thanks to its good mechanical strength and optical clarity, it is ideal for general flow monitoring in industrial processes with moderate requirements. Type GD100 is suitable for a wide range of media, including water, neutral liquids, oil, air, inert gases, and mild cleaning agents. It is suitable for many application areas, such as water treatment, HVAC (heating, ventilation, air conditioning), machinery and plant monitoring, and the food and beverage industry, provided temperature and pH value are within a permissible range.
