Aeroflow stainless steel range of radiator caps for both custom and OEM spec radiators. Keeping the cooling system full is the goal as temperature increases, coolant expands and builds pressure. Higher pressure cap will help in raising the coolant boiling point limit and keep the coolant within the radiator for longer, avoiding any overheating.

Available to suit both the large 42mm and small 32mm radiator neck. They feature an anodised top plate that is riveted to the stainless-steel radiator cap for a smooth finish.

Sold in both silver and black colour options in a 23 PSI (1.58 BAR) pressure rating.
