Durable Construction and Precise Fitment

This Dorman brake hydraulic hose (part number H620466) is built 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 feature 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 connection to the brake system. The included gaskets help maintain a leak-free seal, critical for maintaining hydraulic pressure.
