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.

Porsche Rear Windscreen Seals | Design911 Rubber Weatherstrips for Protection & Structural Integrity
Rear windscreen seals are essential for maintaining your Porsche’s body integrity, weatherproofing, and interior comfort. These precisely moulded rubber components secure the rear glass in position while preventing water, dust, and air leaks. A properly fitted rear windscreen seal protects against corrosion, reduces noise, and ensures the car’s structure remains strong and watertight — vital for both performance and longevity.
At Design911, we supply a premium range of rear windscreen seals and trim sets engineered for perfect fitment and long-term durability. Manufactured from high-quality EPDM and UV-resistant rubber, these seals maintain elasticity, compression, and sealing strength even under extreme weather conditions. Whether for classic Porsche restorations, rear glass replacement, or performance maintenance, our products guarantee lasting protection and precision alignment.
What Do Rear Windscreen Seals Do?
Rear windscreen seals form a watertight and airtight bond between the glass and vehicle body, keeping your Porsche’s interior dry and quiet while supporting structural rigidity.
Core Functions:
• Securely hold the rear glass in position.
• Prevent water, air, and debris from entering the cabin or boot.
• Reduce wind noise and vibration during driving.
• Protect paintwork and interior trim from moisture damage.
• Contribute to aerodynamic performance and body stiffness.
A high-quality rear windscreen seal is vital for maintaining both comfort and structural integrity — particularly on performance or vintage Porsche models.
Why Do Rear Windscreen Seals Fail or Degrade?
Rear glass seals are constantly exposed to sunlight, temperature extremes, and environmental contaminants. Over time, these conditions cause the rubber to deteriorate and lose its sealing effectiveness.
Common Causes of Failure Include:
• UV exposure leading to cracking, hardening, and shrinkage.
• Heat and cold cycles causing deformation and fatigue.
• Contamination from cleaning chemicals or pollutants.
• Moisture ingress weakening the seal bond.
• Age-related wear or improper installation.
When seals degrade, water leaks, wind noise, and corrosion can develop — affecting both cabin comfort and long-term body condition.
Why Replace or Upgrade Your Porsche Rear Windscreen Seal?
Replacing worn or cracked rear windscreen seals restores complete weather protection and prevents costly interior or structural damage. Upgraded materials offer improved flexibility, UV resistance, and compression recovery.
Key Benefits:
• Restores watertight and airtight sealing performance.
• Eliminates leaks, wind noise, and rattling.
• Protects upholstery, wiring, and interior trim from water damage.
• Precision-engineered for Porsche 911, 944, 968 and other classic models.
• Constructed from high-grade, UV-resistant EPDM rubber.
