The rubber O-ring next to a vacuum sight glass serves as a critical seal, ensuring airtight integrity in applications with a temperature range of -15 to +60°C. It prevents the escape of gases or liquids, maintaining the vacuum or pressure within the system.
The O-ring's elasticity allows it to adapt to slight irregularities in the surface of the sight glass and housing, ensuring a reliable seal even under temperature fluctuations. This helps maintain system efficiency, preventing contamination and leakage, and is vital in industries requiring controlled environments, such as food processing, chemical handling, portable toilet emptying etc.
