• 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
