obp Motorsport 52.75oz (1.5 Litre) Horizontal Dark Matter Round Header Tank

This lightweight aluminum coolant header tank (expansion or fill tank) has barbed inlet and outlet fittings for use with rubber coolant hose. The bottom inlet fitting accepts 3/4" ID hose, and the top outlet accepts 3/8" ID hose. The vent (overflow) outlet accepts 5/16" hose. The tank has a built-in mounting bracket on the back. Accepts any standard SAE "A" Size automotive radiator cap (not included). The obp exclusive "Dark Matter" coating provides a tough, matte black finish that looks great. A header tank is recommended for racing applications where the top of the radiator is mounted lower than the top of the engine. Mounting the tank higher than the engine insures a complete fill and provides an air space for expansion.Dimensions:Width: 7 3/4"Diameter of can, without fittings: 4"Depth that bottom barb (3/4" OD) protrudes from can: 1 3/4"Capacity: 1.5 quartsMaximum recommended pressure cap: 30psi   Aluminium Products have always been a core part of obp Motorsport’s product line up. Over recent years we have been inundated with requests from customers for something different than our bare aluminium finish. In response we have created our signature Dark Matter Black Finish.
