Manufactured from high-quality automotive-grade EPDM rubber, the seals are resistant to UV exposure, ozone, moisture and extreme temperature fluctuations. Precision-moulded to match the original factory profile, they ensure excellent flexibility, consistent sealing performance and straightforward installation, making them ideal for vehicle restorations or replacing aged, cracked or deteriorated original seals.  

What This Product Does:

• Creates a weatherproof seal around the front quarter window.
• Prevents water ingress into the cabin.
• Reduces wind noise around the fixed side window.
• Helps prevent dust and road debris from entering the vehicle.
• Cushions the glass to reduce vibration and movement.
• Protects the window aperture against moisture-related corrosion.
• Restores the original appearance and fitment of the quarter window.
• Forms an essential part of the vehicle's body sealing system.

Symptoms Of Wear Or Failure:

• Water leaks around the quarter window.
• Increased wind noise while driving.
• Cracked, split or hardened rubber.
• Shrinking or separation of the seal from the body.
• Visible gaps around the window.
• Moisture entering the cabin.
• Damp interior trim near the window.
• Whistling noises at higher speeds.
• Perished rubber caused by UV exposure.
• Corrosion developing around the window frame.

Why Replacement Matters:

• Quarter window seals are continuously exposed to sunlight, rain, road salt and temperature fluctuations. Over time, the rubber loses flexibility, becoming hard, cracked or shrunken, which reduces its ability to maintain a watertight seal around the glass.
• A deteriorated seal can allow water, dirt and wind to enter the vehicle, leading to increased cabin noise, interior water damage and corrosion around the window aperture. Poor sealing can also affect the appearance of the vehicle and reduce the quality of a restoration.
• Replacing worn quarter window seals restores the weatherproof integrity of the body, improves cabin refinement and helps preserve both the glass and surrounding bodywork. The OE Match replacement provides factory-style fitment, premium EPDM rubber construction and long-lasting durability, helping maintain the originality, comfort and value of your classic Porsche.
