Durable Construction and Design Features

This Dorman brake hydraulic hose (part number H622326) is built with an EPDM rubber hose core that resists heat, ozone, and brake fluid degradation. The black plastic outer sleeve and protective jacket help shield the hose from abrasion and environmental damage. Both ends are equipped with treated steel fittings: a banjo fitting with a 10 mm thread diameter secured by a pinch bolt on one end, and a female inverted flare fitting with an M12 x 1.0 inside diameter on the other. The included gaskets ensure a tight, leak-free connection. Although mounting hardware and brackets are not included, the hose is designed to integrate with existing stamped steel brackets on the vehicle.

Installation Notes and Tips

When installing the Dorman H622326 brake hydraulic hose, ensure the vehicle is securely lifted and the brake system is depressurized.
