A sight glass is a transparent window installed on boilers or burners to allow visual inspection of the flame or fluid level. This component is crucial for monitoring combustion quality and detecting issues like soot buildup or improper flame shape. Made from heat-resistant material, the sight glass provides a clear view without compromising the system's integrity. It is a common spare part for boiler maintenance and repair, enabling quick diagnostics and safe operation. Replace a cracked or clouded sight glass to maintain optimal visibility and safety in your heating equipment.
