Targa Top Seals
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

This original-style rubber seal helps prevent water ingress, wind noise and draughts, making it ideal for replacing worn or deteriorated seals during roof maintenance or classic Porsche restoration.
What Does the Front Windscreen Frame Seal Do?
The seal creates a flexible barrier between the windscreen frame and the roof assembly. It helps prevent rainwater and wind entering the passenger compartment while maintaining correct contact between the roof and bodywork.
Why Does It Fail?
Over time, the rubber can harden, shrink, crack or become permanently compressed. Exposure to sunlight, changing temperatures and repeated roof operation can accelerate deterioration.
A worn seal may cause water leaks, excessive wind noise or visible gaps around the front roof edge.
When Should It Be Replaced?
Replacement is recommended when the seal becomes cracked, flattened, brittle or distorted, or when water and draughts enter around the top of the windscreen.
Inspect the seal whenever carrying out Targa roof refurbishment, hood repairs or windscreen frame maintenance.
Confirm the correct seal against the vehicle's roof design and original part number before ordering.
Checks During Replacement
Inspect the windscreen frame, roof alignment, retaining channels and adjacent weatherstrips. Incorrect roof adjustment or damaged surrounding seals may cause leaks even after fitting a new front seal.
Porsche 911 Targa & Cabriolet Windscreen Frame Seals
The front windscreen frame seal is an important part of the Porsche 911 roof weatherproofing system. It provides a flexible sealing surface between the windscreen frame and the Targa roof or Cabriolet hood.
As original rubber deteriorates, water leaks and wind noise can develop. OE Match seal 91156509047 provides an original-style replacement for selected Porsche 911 Targa and Cabriolet applications from 1967–1985.
Design911 supplies Porsche Targa roof seals, Cabriolet hood weatherstrips, windscreen frame seals and associated restoration components for classic Porsche 911 models.

Designed to replicate the original sealing arrangement, they help create a weather-resistant barrier between the Targa roof and the upper edges of the side windows, reducing water ingress, wind noise and unwanted draughts.
Ideal for replacing hardened, cracked, flattened or damaged original seals during routine Targa roof maintenance, roof refurbishment or a complete classic Porsche restoration.
What Do Targa Top Lateral Seals Do?
The lateral seals run along the sides of the removable Targa roof panel, creating a protective seal against the upper edges of the door glass when the windows are closed.
Their primary functions include:
Helping prevent rainwater entering around the top of the door glass Reducing wind noise at higher road speeds Preventing unwanted draughts entering the passenger compartment Providing a flexible contact surface between the roof and window glass Helping maintain the correct Targa roof sealing arrangement Supporting comfortable, weather-resistant drivingCorrectly fitted lateral seals are particularly important on Targa models because the removable roof and frameless door glass must align correctly to achieve an effective seal.
Why Do Targa Lateral Seals Fail?
Original Targa roof seals are exposed to sunlight, temperature changes, moisture and repeated compression from the door glass.
Over time, the rubber can deteriorate and lose its ability to form an effective seal.
Common causes of failure include:
Rubber hardening through age Cracking or splitting Flattening from prolonged compression Shrinkage or distortion Exposure to UV light and changing temperatures Damage during roof removal or installation Incorrect door glass adjustment Poor roof alignment or worn roof componentsAs the rubber deteriorates, gaps may develop between the window glass and the Targa roof, allowing water and wind noise into the vehicle.
When Should Targa Lateral Seals Be Replaced?
Replacement is recommended whenever the original seals show signs of damage or no longer provide an effective seal.
Typical indications include:
Water entering above the side windows Excessive wind noise around the Targa roof Draughts entering at the top of the door glass Hardened, cracked or split rubber Flattened or permanently compressed sealing surfaces Visible gaps between the roof seal and window glass Loose or distorted sections of weatherstrip Deterioration discovered during Targa roof refurbishmentReplacing worn lateral seals can help restore the original weather protection of the vehicle, provided the roof and door glass are correctly adjusted.
Fitment should be confirmed against the original roof seal profile and vehicle specification, particularly where a replacement or refurbished Targa roof has previously been installed.
Checks During Replacement
When replacing the Targa top lateral seals, inspect the complete roof sealing system to ensure the new rubber provides an effective fit.
Check the front and rear Targa roof seals for deterioration, and inspect the roof frame, retaining components and mounting channels for damage.
The door glass should also be checked for correct height, angle and alignment. Incorrect window adjustment can prevent even a new lateral seal from making proper contact.
Ensure the roof panel sits correctly against the windscreen frame and rear Targa bar before assessing the sealing contact.
Where necessary, adjust the roof and door glass according to the Porsche workshop procedure.
Porsche 911 Targa Roof Lateral Seals & Door Glass Weatherstrips
Maintaining the Targa roof sealing system is essential for protecting the interior of classic Porsche 911 Targa models against water ingress, wind noise and unwanted draughts.
Unlike a fixed-roof Coupé, the Porsche 911 Targa uses a removable roof panel with flexible rubber seals along its front, rear and lateral edges. The side seals are particularly important because they must provide consistent contact with the frameless door glass.
Over time, the original lateral weatherstrips can become hardened, flattened, cracked or distorted, reducing their effectiveness and allowing moisture or wind noise to enter the passenger compartment.
Replacing worn lateral seals helps restore the original roof sealing arrangement, improves contact with the door glass and contributes to a more comfortable driving experience.
These seals are suitable for routine maintenance, Targa roof refurbishment, water leak repairs and complete classic Porsche restoration projects.

The Targa side roof seal is designed to restore proper weather sealing along the side edge of the removable Targa roof panel on classic Porsche 911 models. This precision-moulded rubber seal fits between the Targa top and the side window frame, creating a tight barrier that prevents wind, water, and road noise from entering the cabin.

Old Targa roof seals commonly fail due to UV exposure, compression set, and age. A damaged seal can lead to:
• Water ingress into interior trim and carpets
• Excessive wind noise or whistling
• Poor window alignment and rattles
• Reduced roof stability and overall cabin comfort.
Replacing the seal restores a tight, clean Targa-top closure and protects the interior from the elements.

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.
