NISSAN 90860-VB000 Tailgate Door Vapor Barrier Film

The genuine Nissan (SKU: 90860-VB000) tailgate door vapor barrier film (gasket) is a critical sealing and protective component that prevents moisture, dust, wind, and external contaminants from entering the vehicle passenger cabin and behind the interior trim panels of the luggage compartment.

Key Functions and Features:

• Moisture Protection: Prevents rainwater and moisture infiltrating through exterior gaps or window seals on the tailgate from reaching the interior upholstery, preventing mold formation and unpleasant odors.
• Electrical Component Protection: Effectively protects electrical units located inside the tailgate (central locking actuator, license plate lamps, rear wiper motor, rear-view camera) from corrosion and short circuits.
• Noise and Thermal Insulation: Reduces wind noise and road noise, enhancing ride comfort.

Technical Specifications:

• Manufacturer: Nissan OEM
• Part Number: 90860-VB000
• Product Type: Tailgate door vapor barrier film / seal (Gasket)
• Fitting Position: Rear tailgate (interior, behind the trim panel)
• Material: Durable, tear-resistant, and waterproof polyethylene (PE) film resistant to temperature fluctuations.

Signs of Wear or Damage:

If the vapor barrier film becomes damaged (tears, detaches from the adhesive bead), the following symptoms may occur:

• Water leaks in the luggage compartment, damp carpeting at the base of the rear door.
• Condensation and fogging on interior vehicle windows.
• Intermittent failure of the tailgate electric locking mechanism or rear wiper.

To ensure a complete and long-lasting seal, thorough cleaning and degreasing of the factory mounting surfaces and adhesive contact areas is recommended during replacement.
