What This Product Does:
The upper and rear door window seal acts as a protective guide and sealing channel for the door glass. It supports the window along the upper and rear sections of the frame, helping the glass remain correctly positioned while reducing movement, vibration and exposure to outside elements.

Its key functions include:

• Window Glass Support: Helps guide and support the door glass within the upper and rear sections of the window frame.
• Weather Protection: Helps reduce water and moisture entering through gaps around the door window.
• Wind Noise Reduction: Minimises draughts, whistling and unwanted wind noise caused by poorly fitting window seals.
• Smooth Window Operation: Provides a protective contact surface to help the window glass move correctly within its frame.
• Vibration Reduction: Helps prevent excessive glass movement, rattling and vibration while driving.
• Dust and Dirt Protection: Reduces the entry of road dust, dirt and other environmental contaminants.
• Glass Protection: Helps prevent direct contact between the window glass and surrounding metal frame components.
• Original Appearance: Maintains the factory-style arrangement of the classic Porsche 356 door window assembly.

Common signs include:

• Cracked or Deteriorated Seal: Visible cracking, splitting or general deterioration of the original sealing material.
• Hardened or Brittle Material: Ageing seals may lose flexibility and become less effective at cushioning and supporting the window glass.
• Increased Wind Noise: Whistling, draughts or excessive wind noise around the door window may indicate worn or poorly fitting seals.
• Water Leaks Around the Window: Rainwater or moisture entering around the door glass can indicate deterioration of the sealing system.
• Rattling or Loose Window Glass: A worn guide channel may allow excessive glass movement, particularly when driving over uneven surfaces.
• Difficulty Raising or Lowering the Window: Damaged, distorted or displaced window guides can create resistance during window operation.
• Visible Gaps Around the Glass: Shrinking, wear or incorrect positioning may leave gaps between the window and its surrounding frame.
• Damaged or Worn Guide Surface: Deterioration of the channel's contact surface can affect glass movement and stability.
• Window Misalignment: Excessive wear may allow the glass to sit incorrectly within the door frame.
• Damp Interior Trim: Water entering around deteriorated window seals can lead to moisture accumulation around the door panel and interior.

• Replacing a worn or damaged upper and rear door window seal is an important part of maintaining the comfort, functionality and original condition of your classic Porsche 356.
• As window seals and guide channels age, they gradually lose their ability to support and protect the glass effectively. This can result in rattling, increased wind noise, water ingress and difficulty operating the window.
• A correctly fitted replacement seal helps restore proper window glass guidance and positioning, allowing the glass to move more smoothly while reducing unwanted vibration and contact with surrounding metal components.
• Maintaining effective window sealing is also important for protecting the vehicle's interior. Moisture entering through deteriorated seals can damage door cards, upholstery and internal door components, while prolonged water exposure may contribute to corrosion.
• Replacing deteriorated window seals during restoration or preventative maintenance can help prevent further damage to the window mechanism and surrounding components.
• For Porsche 356 owners, preserving the original window arrangement is essential to maintaining both the driving experience and the authenticity of the vehicle.
• The OE MATCH Upper And Rear Door Window Seal offers a practical OE-style replacement solution, helping restore reliable window operation, effective sealing and the original appearance of the door window assembly.
