常见问题

How often should sight glass on coolant reservoirs be inspected?

Daily visual inspections are recommended during machine operation checks. Complete cleaning and seal inspection should occur during scheduled maintenance, typically every 3-6 months depending on coolant type and operating conditions.

What causes sight glass clouding or discoloration?

Clouding typically results from chemical degradation of the window material due to incompatible coolants, excessive heat exposure, or UV radiation. Discoloration may indicate coolant contamination or chemical reactions between the fluid and window material.

Can sight glasses be used with all types of industrial coolants?

Most standard sight glasses are compatible with water-based coolants and oils. For aggressive chemicals or extreme temperatures, specify borosilicate glass or specialized polycarbonate windows with chemical-resistant seals.
