Rear roll bar seal Targa with plastic rivets and cover plugs
This OE Match rear roll bar seal kit is a complete sealing and installation set designed for Porsche 911 Targa models from 1970 to 1973. The kit includes the rear roll bar rubber seal together with the correct plastic rivets and cover plugs required for proper installation on the Targa roll bar. The seal sits along the front edge of the Targa roll bar, creating the sealing surface between the removable roof panel and the body structure.

Fits:
Porsche 911 1970 - 1973

Diagram ref no 41, 39 and 40.

Kit Includes
  1 × OE Match Rear Roll Bar Seal – 90156509144
  4 × OE Match Porsche Plastic Rivets – 99970318640
  4 × Genuine Porsche Cover Plug for Plastic Rivet – 99959138440

Classic Porsche 911 Targa models use a removable roof panel that locks into the windshield frame at the front and seals against the Targa roll bar at the rear. The rear roll bar seal provides the rubber interface between the roof panel and the roll bar structure.

This OE Match seal is manufactured to replicate the original Porsche seal profile and compression characteristics. It ensures correct fitment and proper sealing performance during installation.

The included plastic rivets and cover plugs secure the seal to the roll bar and provide a clean factory-style finish once installed.

Function
  Weather Sealing: Prevents water leaks around the Targa roof section
  Noise Reduction: Minimises wind noise at the roof-to-body junction
  Roof Fitment: Provides the sealing surface for the removable roof panel
  Cabin Protection: Helps keep the interior dry and protected from debris

Targa roof seals are exposed to UV light, weather and constant compression over many years. As the rubber ages it can harden, shrink or crack, allowing water leaks or wind noise to develop. Replacing the seal and hardware restores proper weather protection and ensures the roof panel fits securely against the roll bar.

Consider replacing the roll bar seal if you notice:
  Water leaks around the Targa roof
  Increased wind noise at highway speeds
  Hardened, cracked or shrunken rubber seal
  During Targa roof restoration or body refurbishment

Rear of roll bar seal.
The rear window to roll bar seal acts as a critical weather barrier, preventing water, wind, and road debris from entering the cabin around the rear glass area. It also helps reduce wind noise and ensures that the Targa top assembly fits cleanly and snugly, maintaining the iconic look and function of the Porsche Targa design.

Fits:
Porsche 911 1965 - 1989
Porsche 964 1989 - 1994

Diagram ref no 23

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

Rear roll bar seal for Porsche Targa models
This seal installs along the front edge of the Targa roll bar, creating the sealing surface between the removable roof panel and the body of the car. Manufactured as an OE Match replacement, the seal replicates the original Porsche profile and fitment to ensure proper roof sealing and factory-correct installation.

Fits:
Porsche 911 1970 - 1973

Diagram ref no 41

The rear roll bar seal sits on the top front edge of the Targa roll bar and forms the contact surface where the roof panel rests.

The OE Match version reproduces the original Porsche rubber gasket in both shape and material quality, providing the correct compression needed to achieve a watertight seal when the roof panel is installed.

The seal prevents water, wind and dust from entering the cabin through the roof-to-body junction. It also stabilises the roof panel and reduces wind noise by maintaining proper contact between the removable roof section and the roll bar.

Replacing worn seals restores the proper weatherproofing and comfort expected from the Targa roof system.

Over time the original rubber seals can harden, shrink or crack due to age, UV exposure and temperature changes. When the seal deteriorates, water leaks and wind noise may develop around the Targa roof area. Installing a new OE Match seal restores proper sealing performance and helps maintain a dry and comfortable interior.

Replace the rear roll bar seal if you notice:
Water leaks from the Targa roof area
• Increased wind noise when driving
Hardened, cracked or shrunken rubber seal
During Targa roof restoration or refurbishment

Rear roll bar seal for Porsche Targa models
The OE Match rear roll bar seal is a weather-sealing component designed for Porsche 911 Targa models from 1970 to 1973. This rubber seal is installed along the front edge of the Targa roll bar, forming the sealing interface between the removable roof panel and the body structure.

Fits:
Porsche 911 1970 - 1973

Diagram ref no 41

The Targa roof system used on classic Porsche 911 models features a removable roof panel and a fixed roll bar behind the seats. The rear roll bar seal  sits on the top/front face of the Targa roll bar, creating a tight sealing surface where the removable roof panel meets the body.

The OE Match version reproduces the original rubber gasket used by Porsche, ensuring the correct shape and compression required for proper roof sealing on early 911 Targa models.

This seal prevents water, wind and dust from entering the cabin at the junction between the removable roof section and the roll bar. It also reduces wind noise and helps maintain a tight, stable fit of the Targa roof panel during driving.

Replacing worn seals restores proper weatherproofing and improves cabin comfort.

Function
  Weather Sealing: Prevents water leaks around the Targa roof section
  Noise Reduction: Minimises wind noise at the roof-to-body junction
  Roof Fitment: Provides the sealing surface for the removable roof panel
  Cabin Protection: Helps keep the interior dry and protected from debris

Roof seals are exposed to sunlight, temperature changes and compression over decades of use. Over time the rubber can harden, shrink or crack, reducing its ability to seal properly and allowing water leaks or wind noise into the cabin. Replacing the seal restores proper roof sealing and helps preserve the interior of the vehicle.

Consider replacing the roll bar seal if you notice:
  Water leaks around the Targa roof
  Increased wind noise at highway speeds
  Hardened, cracked or shrunken rubber seal
  During Targa roof restoration or body refurbishment

About Targa Top Seals

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.

Why Replace or Upgrade Your Porsche Targa Top Seals?

Replacing deteriorated seals restores your Targa’s original refinement and weather protection. Design911’s precision-engineered rubber seals are crafted to match Porsche specifications, ensuring perfect fitment and long-lasting flexibility.
