Durable Construction and Precise Fitment

The Dorman H620782 brake hydraulic hose is constructed with EPDM rubber, known for its resistance to heat, ozone, and brake fluid degradation. The black rubber outer sleeve adds an extra layer of protection against abrasion and environmental factors. Both ends of the hose use treated steel fittings—one banjo fitting with a 10 mm thread diameter and one female fitting with an M10 x 1.0 inside diameter—ensuring a secure and leak-free connection. The hose’s flexible design and 17.75-inch overall length allow for proper installation in the brake system of compatible Chevrolet and GMC heavy-duty trucks.
