Description
ACV Gasket sight glass monobl 557A0149 is a consumable gasket used in boiler and burner systems. It has an outer diameter of 68 mm, an inside diameter of 32 mm, and a thickness of 2 mm. The material designation is gpe. This gasket ensures a gas-tight or water-tight seal between the sight glass and the metal housing, preventing leakage or glass breakage. It is compatible with Prestige 32 MK2, HeatMaster 60, HeatMaster 71, CA 200 Eco, and Compact 28 models.

| Replacement guidance | must be replaced whenever the glass is disturbed during servicing |
| Selection criteria | selected strictly by outer and inner diameter and thickness |
Choosing and fitting
Parts of this type are selected by their outer and inner diameter and thickness, which must match the recess in the sight glass assembly. Before ordering, verify that the new seal is dimensionally identical and rated for the same service (e.g., flue gas side or water side). A mismatch in thickness can prevent the glass from seating correctly or cause uneven clamping. The gasket must be replaced whenever the glass is disturbed during servicing.
Signs of failure
Failure of this kind of gasket can lead to leakage or glass breakage. Symptoms may include visible water or gas leaks around the sight glass, or cracks in the glass due to uneven clamping. Check the gasket for wear, deformation, or hardening, and ensure it is properly seated.
