NISSAN 90820-VC300 Back Door Lower Seal

The genuine Nissan 90820-VC300 back door lower seal (SEAL-BACK DOOR) is a premium-grade, original OEM component engineered to deliver a perfect seal between the rear door and the vehicle body. This seal plays a vital role in shielding the vehicle interior and maintaining cabin comfort.

Key Functions and Features:

• Effective Sealing: Prevents rainwater, moisture, dust, and exterior contaminants from penetrating the cargo compartment, protecting luggage and the vehicle's electrical components from corrosion.
• Noise and Vibration Damping (NVH): Reduces wind noise, road turbulence, and back door vibration during driving, contributing to a quieter cabin.
• Exhaust Gas Protection: Helps prevent exhaust fumes swirling behind the vehicle from drafting back into the passenger cabin.

Technical Specifications:

• Fitting Position: Lower section of the back door / tailgate
• Material: High-density, weather-resistant EPDM rubber (ethylene propylene diene monomer), ensuring superior flexibility and shape retention even under extreme temperature conditions.
• Quality: Genuine Nissan OEM part, guaranteeing precise fitment and long service life.

Signs of Aging and Failure:

Rubber weatherstripping naturally degrades over time due to UV exposure and thermal cycles. Symptoms indicating that replacement is necessary include:

• Moisture or water staining on the trunk lining and carpets.
• Noticeable increase in wind noise or dust accumulation along the cargo area perimeter.
• Visible cracks, tears, hardening, or crumbling on the rubber surface.
• Improper or uneven closure of the back door.

Using a genuine Nissan seal restores your vehicle's factory sealing integrity and acoustic insulation.
