The sight glass gasket is a sealing component used in boiler sight glasses to prevent leaks around the viewing window. It ensures a tight seal between the glass and the housing, allowing clear observation of the flame or water level. This gasket is typically made from heat-resistant material. Replacing a worn or damaged gasket restores the integrity of the sight glass, enabling safe monitoring of your heating system.
