Rear Window Seal.
The OE Match Rear Window Seal is a premium-quality replacement weather seal designed to provide a secure, watertight seal around the rear window on compatible classic Porsche models. Manufactured to OE specifications for fit, profile and durability, this rear screen seal restores the original factory fit while protecting the vehicle interior from water, wind, dust and road contaminants.  

Fits:

• Porsche 356B 1959-63
• Porsche 356C 1963-65 

Diagram Ref No 37

Manufactured from high-quality automotive-grade EPDM rubber, the seal offers outstanding resistance to UV exposure, ozone, moisture and extreme temperature changes. Precision-moulded to match the original factory profile, it ensures excellent flexibility, secure glass retention and long-lasting sealing performance, making it ideal for restoration projects or replacing hardened, cracked or deteriorated original seals.  

What This Product Does:

• Creates a weatherproof seal around the rear window.
• Secures the rear glass firmly within the body aperture.
• Prevents water, dust and road debris from entering the cabin.
• Reduces wind noise while driving.
• Helps protect the window aperture against corrosion.
• Cushions the glass to minimise vibration and stress.
• Restores the original fit and appearance of the rear window.
• Forms an essential part of the vehicle's body sealing system.

Symptoms Of Wear Or Failure:

• Water leaks into the cabin or luggage compartment.
• Increased wind noise around the rear window.
• Cracked, split or hardened rubber.
• Shrinking or separation of the seal from the body.
• Visible gaps around the rear glass.
• Damp carpets or interior trim.
• Condensation caused by water ingress.
• Loose or poorly supported rear window.
• Perished rubber due to age or UV exposure.
• Corrosion developing around the rear window frame.

Why Replacement Matters:

• The rear window seal is constantly exposed to sunlight, rain, road salt and changing temperatures. Over time, the rubber can lose its flexibility, becoming hard, brittle or cracked, reducing its ability to maintain a watertight seal around the glass.
• A deteriorated seal can allow water and dirt to enter the vehicle, leading to interior damage, corrosion around the window aperture and increased wind noise. If left unattended, moisture trapped around the rear window frame can contribute to costly bodywork repairs, particularly on classic Porsche models.
• Replacing a worn rear window seal restores the weatherproof integrity of the vehicle, improves cabin comfort and protects both the interior and surrounding bodywork. The OE Match replacement provides factory-style fitment, premium EPDM rubber construction and long-lasting durability, helping preserve the originality, appearance and value of your Porsche.
