ARISTON Flange Gasket for PRO R / BLU R / PRO ECO, 65111788

ARISTON 65111788 is a rubber gasket for a round 5-hole water-heater flange, designed to provide a watertight seal between the water-heater tank and the flange assembly.

The gasket is used in compatible ARISTON PRO R, PRO ECO, PRO PLUS and BLU R storage water heaters, as well as in several BLU1 R and LYDOS series constructions.

The spare part is intended for a round flange with 5 mounting holes. Its function is to seal the flange connection and prevent water leakage from the storage tank.

Spare-parts catalogues specify an outside diameter of approximately 89–91 mm and an inside diameter of approximately 36 mm. Slightly different dimensions may be stated depending on the measurement method.

When servicing the flange, heating element or magnesium anode, the condition of the gasket should also be checked. If it has hardened, deformed, cracked or become damaged, replacement is recommended.

Before ordering, check the exact water-heater product code and confirm that the appliance uses ARISTON 5-hole flange gasket 65111788.
