Internal hose degradation and environmental exposure can lead to pressure loss, uneven caliper response, and dangerous fluid leaks in brake systems. This replacement hydraulic line provides a structural upgrade to restore instantaneous hydraulic response and eliminate internal line collapse or volumetric expansion under heavy fleet stopping conditions.
Constructed with heavy-wall reinforcement and rated for high burst pressures, the DFC 350-47337 brake hose ensures reliable performance in severe-duty applications. Its drop-in fitment makes installation straightforward, restoring proper hydraulic flow while resisting external chafing and abrasion common in commercial vehicle environments.
- Overall Length: 18-inch overall length
- Fitting / Outlet Size: 10mm INV thread size
- Application: Commercial-Grade / Heavy-Duty Fleet / Passenger Automotive Cross-Over
Part Numbers
- `350-47337`
Expert Installation & Field Note
Our shop experience specializing in heavy-duty brakes since 1985 emphasizes the importance of proper hose routing to prevent chassis chaffing and ensure full-lock steering clearance. Always verify the existing line length, banjo fittings, and flare thread threads before ordering, as fleet and utility applications often feature mid-year production changes or varying wheelbase configurations that alter line routing. Proper line mounting on heavy-duty frames is critical to prevent premature wear and maintain hydraulic integrity over time.
Before ordering, physically inspect your existing brake line, banjo fittings, or flare threads. Mid-year production runs and different wheelbase configurations can significantly change routing and fitting requirements. Confirm dimensions and thread sizes to ensure compatibility with your specific vehicle application to avoid installation delays or system failures.
