Nuova Rade Inox Deck Fillers with Cap are suitable for fuel, fresh water or waste. The use is easily indicated by the colour of the cap: blue for fresh water, red for fuel and brown for waste. The main body is made of reinforced PA. The cap is made of Inox 316 and reinforced PA for endurance and extra durability in the marine environment. The cap features a lanyard in order not to be lost or fall into the water. These deck fillers have a tight fitting, as they can be secured with the use of a winch handle.
