Manufactured According to DIN 7080 Standard
DIN 7080 Sight Glass is designed based on the requirements for circular thermally toughened borosilicate glass discs used in industrial observation equipment.
The strict standard requirements ensure reliable dimensional accuracy, surface quality, and mechanical performance. This makes DIN 7080 glass discs suitable for standardized sight glass assemblies used in industrial machinery and pressure equipment.
VATTI controls the manufacturing process carefully, including raw material selection, thermal toughening, precision processing, and quality inspection, ensuring consistent performance for industrial applications.
Excellent Thermal Resistance and Thermal Shock Performance
One of the most important advantages of DIN 7080 Sight Glass is its outstanding resistance to temperature changes.
Manufactured from Borosilicate Glass 3.3, the glass features a low coefficient of thermal expansion, allowing it to maintain stability under extreme temperature fluctuations.
The heat resistant sight glass can withstand rapid heating and cooling cycles, making it suitable for applications such as:
· Industrial boilers
· Steam equipment
· Chemical processing systems
· Sterilization equipment
· High-temperature reactors
Its excellent thermal shock resistance helps reduce the risk of cracking caused by sudden temperature differences and improves operational reliability.
High Mechanical Strength for Industrial Equipment
DIN 7080 Sight Glass is produced through a thermal toughening process that significantly improves mechanical strength compared with standard glass.
The reinforced glass structure provides better resistance against mechanical stress and pressure conditions, making it suitable for pressure vessel sight glass applications.
The circular disc design helps distribute stress evenly, providing stable installation performance when mounted between sealing components.
For industrial equipment requiring reliable visual inspection under pressure conditions, DIN 7080 Borosilicate Glass Disc provides a durable and dependable solution.
Superior Chemical Resistance
Industrial equipment often operates in environments involving water, steam, acids, alkalis, and chemical media. DIN 7080 Sight Glass provides excellent chemical durability due to the properties of Borosilicate Glass 3.3.
The material maintains surface integrity and optical clarity during long-term exposure to demanding environments, making it widely used in:
· Chemical processing equipment
· Pharmaceutical machinery
· Food processing systems
· Laboratory equipment
· Industrial reaction vessels
This chemical resistance helps extend service life and reduce replacement frequency.
Clear Observation and Optical Performance
Reliable visual monitoring is essential for many industrial processes. DIN 7080 Sight Glass provides excellent transparency and surface clarity, allowing operators to observe internal equipment conditions effectively.
The polished glass surface supports clear inspection of:
· Liquid levels
· Material flow
· Reaction processes
· Equipment operation status
This makes it an ideal industrial inspection window glass solution for applications requiring both durability and visibility.

DIN 7080 Sight Glass is widely used in boiler systems and thermal equipment where continuous observation is required under high temperature conditions.
Its excellent heat resistance and mechanical strength make it suitable for monitoring internal conditions while maintaining reliable operation.
Pressure Vessel Observation Windows
Pressure vessels require inspection components that can withstand both mechanical stress and temperature changes.
DIN 7080 Borosilicate Glass Disc provides a reliable viewing solution for tanks, vessels, and industrial equipment requiring safe visual monitoring.
Chemical and Process Equipment
Chemical processing equipment often requires glass materials with excellent resistance to corrosion and thermal stress.
DIN 7080 Sight Glass is suitable for reactors, processing tanks, and industrial systems where clear observation and long-term durability are required.
Pharmaceutical and Food Processing Equipment
The pharmaceutical and food industries require reliable materials with good chemical stability and thermal performance.
DIN 7080 Sight Glass can be applied in processing equipment, sterilization systems, and sanitary observation windows where clean and reliable inspection is necessary.
DIN 7080 Sight Glass is designed as a circular flat glass disc with precision-controlled dimensions and polished surfaces. The disc structure enables uniform stress distribution during operation and provides reliable sealing performance when installed between suitable gaskets and flange systems.
The combination of thermally toughened Borosilicate Glass 3.3 and precision surface processing ensures stable performance under pressure, temperature fluctuations, and industrial operating conditions.
The main structural characteristics include:
· Circular disc design for even mechanical stress distribution
· Parallel polished surfaces for clear observation
· Controlled thickness according to pressure requirements
· Smooth edges to reduce installation-related stress concentration
This design makes DIN 7080 Sight Glass suitable for standardized sight glass fittings used in industrial equipment.
The performance of DIN 7080 Sight Glass mainly depends on the excellent properties of Borosilicate Glass 3.3.
Compared with conventional glass materials, Borosilicate Glass 3.3 offers:
Low Thermal Expansion
The low coefficient of thermal expansion reduces internal stress caused by temperature changes, improving resistance against thermal shock.
High Chemical Durability
The glass provides excellent resistance against water, acids, and alkalis, ensuring stable performance in corrosive environments.
Long-Term Optical Stability
The material maintains high transparency and surface quality during long-term industrial operation.
These characteristics make thermally toughened Borosilicate Glass 3.3 the preferred material for DIN 7080 Sight Glass applications.
Proper installation is essential to achieve reliable performance and extend service life.
Recommended installation practices include:
Use Suitable Gaskets
The glass disc should be installed with appropriate sealing gaskets to prevent direct contact between glass and metal components.
Ensure Clean Sealing Surfaces
Flange surfaces should be clean, flat, and free from particles that may create uneven stress.
Avoid Excessive Mechanical Stress
Fasteners should be tightened evenly to avoid localized pressure on the glass disc.
Following correct installation procedures helps prevent premature damage and ensures safe operation.
