NISSAN 92490-VC811 High-Pressure Flexible A/C Hose

The Nissan 92490-VC811 genuine (OEM) high-pressure flexible A/C hose is an essential component of the vehicle's air conditioning system. Its function is to safely transport the high-pressure, high-temperature refrigerant compressed by the compressor toward the condenser.

Technical Features and Construction

• Type: High-pressure flexible A/C hose (Hose-Flexible, High)
• Material Composition: Specialized multi-layer fiber-reinforced rubber (barrier hose) and corrosion-resistant metal (aluminum/steel) fittings
• Vibration Damping: Flexible design absorbs vibrations caused by engine movement, protecting rigid lines from cracking
• Pressure Resistance: Specifically engineered for the high operating pressures of the A/C system

Typical Symptoms of Failure

• Leakage: Oily, dusty deposits on the hose surface or at the metal fittings (caused by leaking compressor oil circulating with the refrigerant)
• Reduced Cooling Performance: Deterioration of A/C system efficiency resulting from pressure loss due to leaks
• Visible Damage: Cracks, surface wear, or chafing on the rubber section

Maintenance Recommendation

When replacing the A/C hose, it is always recommended to use new sealing rings (O-rings), as well as evacuate and recharge the system in accordance with factory specifications.
