OE Match front windscreen seal for Porsche 356 / 356A / 356B / 356C. This replacement rubber seals the junction between the front glass and body aperture.
Fits
- Porsche 356 Coupe 08/1950 - 12/1965
Diagram ref no: 2
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
The windscreen rubber forms a weather barrier around the glass, helping to keep rain, draughts and dust outside the cabin. It is relevant when renewing deteriorated sealing rubber or undertaking glazing work during restoration.
Functions
- Seals the perimeter of the front glass against the body.
- Helps limit moisture entry around the windscreen opening.
- Closes gaps that can admit air and cause whistling.
Technical Details
- Part reference: 64454190100. Brand: OE Match.

- Window glazing 356B / 356C 1960-65: item 11; engine/model: 356 B-T6356 CCOUPE-KARMANN-.
Symptoms of Fault
- Rainwater tracks appearing around the glass or dashboard.
- Whistling from the screen perimeter while driving.
- Rubber that has become brittle, split or visibly contracted.
- Persistent cabin dampness or musty odours associated with leakage.
Why Replacement Matters
Ageing rubber can lose flexibility and pull away from sealing surfaces. Renewing a deteriorated windscreen seal helps address these gaps and reduce moisture reaching interior trim. Inspect the surrounding aperture as well: damaged surfaces or corrosion may need attention before new rubber is installed.
FAQs
Can rubber treatment restore an old seal?
A conditioner may offer temporary improvement, but it will not repair splits or reverse significant shrinkage.
What should be checked before fitting?
Confirm the body style and production details, compare the original seal and clean the contact surfaces. Avoid stretching the rubber during installation.
Does every water leak indicate seal failure?
No. Establish where moisture enters and inspect the aperture and adjoining components before replacing parts.

Porsche Front Windscreen Seals | Design911 Rubber Weatherstrips for Clear Visibility & Cabin Protection
Front windscreen seals are critical to your Porsche’s comfort, visibility, and protection. These precision-moulded rubber components secure the glass in place while preventing water, dust, and wind noise from entering the cabin. A properly sealed windscreen not only ensures clear visibility but also maintains the vehicle’s structural integrity — keeping the interior dry, quiet, and secure in all conditions.
At Design911, we offer a full range of front windscreen rubber seals and trim sets engineered for long-lasting flexibility and exact fitment. Manufactured from premium-grade EPDM and UV-resistant rubber, these seals deliver outstanding durability and sealing performance. Ideal for restorations, repairs, or detailing upgrades, our windscreen seals preserve the appearance, comfort, and safety standards your Porsche deserves.
What Do Front Windscreen Seals Do?
Front windscreen seals (also known as windshield weatherstrips) create a tight bond between the glass and the vehicle body, ensuring both safety and comfort.
Core Functions:
• Secure the front glass firmly to prevent movement and leaks.
• Seal the cabin from water, dust, and air intrusion.
• Reduce wind noise and vibration for a quiet drive.
• Protect the dashboard, trim, and electronics from moisture damage.
• Support aerodynamic flow and proper glass alignment.
A high-quality seal maintains visibility and weatherproofing, protecting both the driver and the vehicle’s structure over time.
Why Do Front Windscreen Seals Fail or Degrade?
Constant exposure to sun, weather, and pressure changes causes gradual degradation of the rubber material, leading to leaks or poor fitment.
Common Causes of Failure Include:
• UV and ozone exposure causing cracking or hardening.
• Compression fatigue from repeated thermal expansion.
• Contamination from cleaning products or environmental debris.
• Improper installation or aged adhesive surfaces.
• Corrosion along the windscreen frame weakening the seal.
When windscreen seals fail, drivers often experience water leaks, wind noise, fogging, or even structural weakness around the windshield area.
Why Replace or Upgrade Your Porsche Front Windscreen Seal?
Replacing your Porsche’s front windscreen seal ensures a watertight, secure, and noise-free fit. Modern sealing materials offer improved elasticity, UV protection, and resistance to temperature fluctuations.
Key Benefits:
• Restores watertight sealing and prevents interior leaks.
• Eliminates wind noise, vibration, and glass movement.
• Protects dashboard and cabin components from moisture.
• Constructed from premium-quality rubber for long service life.
• Fits Porsche 911, 944, 968, Boxster, Cayman, and Panamera models.
• Ideal for restorations, windshield replacement, and detailing projects.
Design911’s Porsche front windscreen seals combine precise engineering and advanced materials for a perfect seal, ensuring lasting comfort and protection for every drive.
