A colour ring allows to identify the use of the aluminium deck fillers :
The cap recess is reinforced with an aluminium coating to allow the safe use of opening keys or winch handles with no risk of distortion.
The water fibreglass deck filler is available with or without a hose stopper. The hose stopper prevents a deep entry of the hose into the tank, avoiding overpressure and potential tank bursting or cracking.
The emergency deck plate features a mirror polish finish and a 1/8 quick twist cap. It provides optimum security compared with a threaded model and prevents jamming in the long term.
