Universal aluminum coolant expansion and overflow tank with cap

Key Features & Benefits – universal aluminum coolant expansion tank

The universal aluminum coolant expansion tank is suitable for systems that use 19mm inlet/outlet connections and a separate remote reservoir. The aluminum body comes with a 1 bar pressure release cap, and capacity is 1.2L.

The 103mm diameter and 160mm length provide a useful reference for layouts where filling and bleeding are easier through a separate tank. It can be used in car, motorcycle, quad, electric vehicle, kit car and boat projects when the connection size and installation space match.

When is this useful?

This tank is useful when a cooling system needs a separate filler, expansion or overflow unit and the setup benefits from a compact size, 19mm hose connections and a basic tank-and-cap package.

Selection & installation tips

• Hose size: confirm that the system uses 19mm internal hose size and that your clamps match that connection.
• Installation space: compare the 103mm diameter and 160mm length against the available space, and leave enough clearance to open the cap.
• System pressure: check that the 1 bar cap matches the intended cooling system setup.
• Package contents: the package includes the tank and cap, so verify hoses, clamps and the mounting solution separately.

Before installation, self-check hose size, available space, cap pressure and mounting points, then compare them with the listed details.
