Durable Construction and Design Features

This Dorman brake hydraulic hose (part number H38121) is constructed with EPDM rubber, known for its resistance to heat, ozone, and brake fluid. The black rubber outer sleeve adds an extra layer of protection against abrasion and environmental factors. Both ends of the hose are fitted with treated steel connectors—one banjo fitting with a 0.38-inch thread diameter and one female fitting with a 3/8 in-24 inside diameter—ensuring a secure and leak-free connection. The included gaskets help maintain a tight seal, preventing brake fluid leaks. The flexible hose design allows for smooth movement and vibration absorption within the brake system.
