The protective ring Bilbao D500 is a replacement structural part intended for Bilbao series filter tanks with a diameter of 500 mm.
A correctly fitted ring protects the upper edge of the filter tank from mechanical damage during mounting and removal of the lid.
The use of an original part guarantees a precise fit and prevents water leakage in the area of the tank closure.
Replacement is easy and requires no professional tools – just remove the tank lid and fit the ring onto the body of the filter tank.
