New - Aero 400 Roll Over, Vented, Centre Cap - Silver

New - Aero 400, Vented, Roll Over, Centre Cap Only Specialist Centre Cap to allow airflow into a tank whilst preventing vehicle rollover fuel leaks. This product provides free ventilation until the fuel tank / cell becomes inclined to an angle of more than 50+ degrees or acceleration/ deceleration when fuel is trying to surpass the valve area, the floatation ball seals the vent shut preventing fuel from escaping. When in an accident, the vehicle is upside down or on the side 90 degrees, the stainless-steel ball (acting under gravitational forces) seals the vent shut preventing fuel from escaping. The Vented Filler Caps allows the fuel tank to maintain a constant and safe status by minimising build-up of pressure and allowing the tank to vent should a vacuum be experienced.
