Bonnet / Boot Seals
This gasket fits around the rear hatch opening and provides a tight seal when the hatch is closed, helping keep water, dust, and exhaust fumes out of the rear compartment and protecting the interior and cargo space.
Fits:
Porsche 928 1978 - 1986
Diagram ref no 6
• Location: Rear hatch / tailgate perimeter - one seal per vehicle
• Usage Cases: Hatch restoration, leak repair, water ingress prevention, full restoration, or replacement of cracked/old seals
It’s ideal for restoring a 928 with a deteriorated, hardened, or missing hatch seal - ensuring the rear compartment remains properly sealed against the elements and road contamination.
Over time, the original rear hatch seal can become brittle, compressed, torn, or lose elasticity - often resulting in:
• Water leaks into the rear compartment or boot area
• Dust, exhaust fumes or road spray entering the cabin
• Increased cabin noise and reduced comfort
• Corrosion, mildew, or damage to interior panels and wiring
Replacing with a correctly formed seal restores proper weatherproofing, preserves interior condition, and ensures the hatch closes securely and cleanly - essential for longevity, comfort and preserving vehicle value.

Porsche Bonnet & Boot Seals | Design911 Rubber Weather Seals for Body Protection & Longevity
Bonnet and boot seals are vital to preserving the integrity, comfort, and appearance of your Porsche. These precision-fitted rubber seals prevent water, dust, and wind from entering the luggage compartments, ensuring a clean, quiet, and protected environment. In both classic and modern Porsche models, maintaining proper sealing is essential for preventing corrosion, electrical damage, and interior deterioration.
At Design911, we supply a comprehensive range of bonnet and boot rubber seals, designed for an exact fit and long-lasting performance. Manufactured from premium-grade weather-resistant materials, our seals deliver exceptional flexibility, compression recovery, and durability. Whether for restoration, maintenance, or performance detailing, Design911’s sealing components provide professional-grade protection and finish for every Porsche.
What Do Bonnet & Boot Seals Do?
Bonnet and boot seals create a tight barrier between the body panels and the luggage compartments, shielding your Porsche’s structure and interior from external elements.
Core Functions:
• Prevent water, dirt, and air leaks into front and rear compartments.
• Reduce noise, vibration, and harshness (NVH) during driving.
• Protect paintwork and body edges from friction damage.
• Assist with proper panel alignment and secure closure.
• Maintain optimal pressure sealing for climate protection.
High-quality rubber seals are essential for keeping your Porsche dry, quiet, and free from unwanted wear — enhancing both comfort and longevity.
Why Do Bonnet & Boot Seals Fail or Degrade?
Rubber components naturally deteriorate over time due to environmental exposure, pressure cycles, and age-related hardening.
Common Causes of Failure Include:
• UV and ozone damage causing cracking and brittleness.
• Compression set from repeated opening and closing of panels.
• Contamination by oil, fuel, or cleaning chemicals.
• Deformation or tearing from misaligned panels or closures.
• Age-related loss of elasticity reducing sealing effectiveness.
Once seals begin to fail, moisture and dust can infiltrate compartments, leading to corrosion, noise, and costly repairs — making timely replacement crucial.
Why Replace or Upgrade Your Porsche Bonnet & Boot Seals?
Replacing your Porsche’s bonnet or boot seals restores the original comfort, protection, and aesthetic integrity of your car. Upgraded rubber compounds offer improved sealing and longevity over standard materials.

• Restores water- and air-tight sealing for front and rear compartments.
