Designed as an original-style replacement fixing, this plastic rivet helps retain the Targa roof weather seal in its correct position, supporting a secure fit and maintaining the original roof sealing arrangement.
Ideal for replacing broken, missing or damaged original rivets during Targa roof seal replacement, roof refurbishment or classic Porsche restoration.
What Does the Targa Seal Plastic Rivet Do?
The plastic rivet is used to secure the Targa roof seal to its designated mounting position.
The Targa roof relies on correctly fitted weather seals to help prevent water, wind and road noise from entering the passenger compartment.
This retaining rivet helps keep the seal correctly located, preventing unwanted movement or displacement during roof installation, removal and normal vehicle use.
Although small, it is an important fixing component when maintaining or restoring the Targa roof sealing system.
Why Do Targa Seal Plastic Rivets Fail?
Plastic retaining rivets can deteriorate over time, particularly on classic Porsche vehicles where the original fittings may be several decades old.
Common causes of failure include:
- Plastic becoming brittle through age
- Exposure to sunlight and temperature changes
- Damage during Targa roof seal removal
- Repeated roof maintenance and refurbishment
- Incorrect removal or installation
- Cracking or breaking of the retaining head
- General wear and deterioration
Once damaged, the rivet may no longer hold the seal securely in its intended position.
When Should It Be Replaced?
Replacement is recommended whenever a plastic rivet is broken, missing, loose or no longer provides secure retention.
Typical signs include:
- Missing Targa seal fixing points
- Broken or cracked rivet heads
- Loose or displaced sections of weather seal
- Rivets damaged during seal removal
- Brittle or deteriorated original plastic
- Insecure fitting following roof refurbishment
It is advisable to inspect the retaining rivets whenever replacing or adjusting the Targa roof seals.
Checks During Replacement
When replacing the Targa seal plastic rivet, inspect the surrounding roof sealing components.
Check that the weather seal is correctly positioned and free from splits, distortion or excessive compression.
Inspect the retaining holes and mounting surfaces for damage, ensuring the replacement rivet can be fitted securely without excessive force.
If the roof seal has become hardened, flattened or damaged, replacing the rivet alone may not resolve wind noise or water leaks.
Ensure all retaining points are correctly secured before refitting or adjusting the Targa roof.
Porsche 911 & 964 Targa Roof Seals, Plastic Rivets & Weatherstrip Fixings
Maintaining the Targa roof sealing system is essential for protecting the interior of classic Porsche 911 and 964 Targa models against water ingress, wind noise and unwanted draughts.
The Targa roof uses a combination of rubber weather seals, retaining components and carefully positioned mounting points to achieve an effective seal between the removable roof panel and the vehicle body.
Over time, original plastic retaining rivets can become brittle, cracked or damaged, particularly when removing aged roof seals during restoration work. Replacing damaged or missing retaining rivets helps ensure that the Targa weather seals remain correctly positioned and securely attached.
This small but important component is particularly useful during Targa roof refurbishment, weatherstrip replacement, leak repairs and complete classic Porsche restoration projects.

• Application: Fits rear glass to roll bar sealing interface on classic Targa cars. One seal per car. Designed to match original factory dimensions and mounting locations for a direct replacement fit.
• Function: Weatherproofing between rear glass & roll bar
• Benefits: Prevents leaks, reduces noise, restores original fit & finish
Installed along the top edge of the rear glass where it meets the Targa roll bar, this gasket provides a consistent sealing surface that keeps out moisture and airflow while preserving the structural integrity and classic silhouette of your Porsche. It supports long-term durability for road driving and contributes to the car’s overall comfort and weather resistance.
Over time, the original rear window seal can harden, crack, or compress due to aging, UV radiation, and temperature fluctuations. When the seal isn't functioning properly, moisture can leak into or into the cabin, causing water spots, fogging, and potential corrosion. Replacing this seal with a new, high-quality seal restores proper weather protection, keeps the interior dry and quiet, and helps preserve the value and authenticity of your classic Porsche.
Replace the rear Targa roll bar seal if you notice:
• Cracks, splits, or visible hardening of the seal
• Water leaks or dampness around the rear window
• Increased wind noise at higher speeds
• Loose or compressed seal no longer providing firm contact
• During restoration or Targa top refurbishment

Targa Top Seals - Precision Weather Sealing for Wind, Water & Noise Protection
Targa top seals are essential components that maintain the watertight and airtight integrity of your Porsche’s removable roof system. Designed to fit around the roof edges, side glass, and windscreen frame, these seals prevent wind noise, vibration, and water ingress — ensuring a quiet, comfortable, and leak-free driving experience. Over time, environmental exposure and repeated compression cause rubber seals to harden, crack, or shrink, making replacement crucial to preserve cabin comfort and vehicle protection.
At Design911, we offer a premium range of Targa top seals engineered for exact fitment, flexibility, and long-lasting performance. Each seal is crafted from high-grade rubber compounds resistant to UV, ozone, and temperature extremes, ensuring a perfect fit and dependable sealing for years to come. Whether for restoration, maintenance, or weatherproofing upgrades, our seals deliver the precision and durability expected by Porsche enthusiasts worldwide.
What Do Targa Top Seals Do?
Targa top seals are designed to create a continuous barrier between the removable roof panel and the bodywork, protecting against external elements.
Core Functions:
• Prevent water, wind, and dust from entering the cabin.
• Reduce wind noise and vibration at high speeds.
• Maintain proper roof alignment and pressure sealing.
• Protect interior trim and electronics from moisture damage.
• Ensure long-term comfort, safety, and weather resistance.
Properly fitted seals are key to preserving the driving refinement and structural integrity that make the Porsche Targa experience unique.
Why Do Targa Top Seals Fail or Degrade?
Exposure to sunlight, heat cycles, and movement over time can cause rubber materials to lose flexibility and sealing strength.
Common Causes of Failure Include:
• UV and ozone exposure causing hardening and cracking.
• Compression set from repeated roof removal or long-term storage.
• Deformation or shrinkage due to temperature fluctuations.
• Water or dirt contamination leading to surface wear.
• Improper alignment or fitting causing gaps and leaks.
When seals fail, symptoms include increased wind noise, water leaks, rattling panels, and a loose roof fit — all of which impact comfort and performance.
