Durable Construction and Design Features

The Dorman H621665 brake hydraulic hose features a flexible EPDM rubber hose core that resists heat, ozone, and brake fluid degradation. The black plastic outer sleeve protects the hose from abrasion and environmental damage. Both ends are equipped with treated steel fittings—one banjo type with a 10 mm thread diameter and one female fitting with an M12 x 1.0 inside diameter—ensuring a secure and leak-free connection. The included stamped steel bracket and gaskets facilitate proper mounting and sealing, maintaining brake system integrity.
