What Does This Part Do? – Functions

• Weather Protection: Helps prevent rainwater, dust and road debris from entering the cabin.
• Wind Noise Reduction: Minimises unwanted air movement around the door edges.
• Secure Sealing: Creates a protective seal between the door and vehicle body.
• Vibration Reduction: Helps cushion contact and reduce door-related rattles.
• Original Fitment: Maintains the factory door sealing arrangement.

Why Replace This Part?
Over time, door seals can become hardened, cracked, compressed or damaged due to ageing, sunlight and moisture exposure. A deteriorated seal may allow water and wind to enter the cabin, causing increased road noise, interior moisture and potential corrosion around the door openings.

Replacing worn seals with genuine Porsche components helps restore effective weather protection, improve cabin comfort and preserve the original condition of your classic Porsche 356.

When to Replace This Part?

• Cracked Rubber: Visible splits, tears or deterioration.
• Water Leaks: Moisture entering around the door edges.
• Wind Noise: Increased noise caused by poor door sealing.
• Hardened Seals: Rubber becoming brittle or losing flexibility.
• Loose Fitment: Seal becoming detached or incorrectly positioned.
• Restoration Work: During door repairs or classic Porsche restoration.

Where Does It Fit on the Car?
Location: Inner door edges – front or rear, depending on model year.

The rubber seal is fitted directly to the inner edge of the door, creating a protective barrier where the door meets the surrounding bodywork.

It is traditionally bonded to the door using a suitable automotive weatherstrip adhesive.
