Targa Top Lateral Seals (Over Door Glass)
OE Match replacement Targa top lateral rubber seals. These
seals are fitted along the left and right sides of the removable Targa roof
panel, directly above the door glass.

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.
