Sight Glasses for Vacuum Pumps

A sight glass is a useful feature of most vacuum pumps, as it allows you to check the state of the oil inside the pump without opening it. The oil plays an important role in lubricating and sealing the pump, as well as removing heat and contaminants from the process gas. Therefore, it is essential to keep the oil clean and free of impurities that can degrade its performance and cause damage to the pump. 

However, over time, the oil can become dirty and dark due to exposure to air, moisture, dust, and other substances that enter the pump. This can affect the pump's efficiency and reliability, as well as increase the risk of corrosion and wear. To prevent these problems, you should regularly inspect the oil through the sight glass and replace it when it becomes too dark or cloudy.
