Durable Construction and Design Features

This Dorman brake hydraulic hose (part number H621667) is built with EPDM rubber, known for its resistance to heat, ozone, and brake fluid degradation. The black plastic outer sleeve and protective jacket help shield the hose from abrasion and environmental damage. The treated steel fittings—banjo type on one end with a 10 mm thread diameter and female fitting on the other with an M12 x 1.0 inside diameter—ensure a secure connection to the brake system. Although mounting hardware and brackets are not included, the stamped steel bracket material specification indicates compatibility with existing vehicle components.
