Motorcraft Tubes and Lines are engineered to provide superior performance and reliability. Each design undergoes rigorous lab and real world tests to ensure long life and optimum performance under harsh operating conditions.
Features & Benefits
High quality materials are used to help withstand vibration, extreme temperatures and harsh chemicals as well as cracks, damage and leakage
Must pass tests for resistance to static and dynamic pressure, burst pressure and temperature extremes
Burst testing subjects the lines to over 1,750 PSI to help ensure hose and fittings integrity when subjected to high temperatures
Vibration tested to detect unwanted resonance noises
Must pass 1,000 hour leak tests to help ensure corrosion resistance
Flexible tube sections are reinforced with braided polyester for added strength
Foam insulators help protect against chafing and possible under hood rattles
Hard lines are pre bent to fit and mounting brackets are included, where applicable
