The OE Match Vent Window Seal is a replacement rubber sealing frame for the opening front vent window fitted to selected early Porsche 911 and 912 Targa models.

Diagram Ref No 16
Mounted around the perimeter of the small opening vent glass, the seal creates a flexible weather-resistant barrier between the glass and its surrounding frame. Its job is to help keep rainwater, wind and road contamination outside the cabin while allowing the vent window to open and close correctly.
Over time, the original rubber can harden, flatten, crack or shrink as a result of UV exposure, heat, cold and repeated compression. Once the seal loses its elasticity, it may no longer sit firmly against the glass, resulting in water leaks, wind noise, rattling or poor vent-window closure.
Replacing a deteriorated vent-window seal helps restore weather protection, reduce cabin noise and preserve the fit and appearance of the original Targa window assembly.
What This Product Does:The Vent Window Seal forms the weatherproof contact surface between the opening vent glass and its frame.
Its main functions are to:
- Help prevent rainwater entering around the vent window.
- Reduce wind noise while driving.
- Prevent dust and road contamination entering the cabin.
- Cushion the vent glass against the surrounding frame.
- Help maintain correct glass positioning.
- Reduce rattles and vibration.
- Support smooth vent-window closure.
- Restore the original appearance of the window assembly.
Symptoms Of Wear Or Failure:
Common symptoms include:
- Water entering around the vent window.
- Wind noise at speed.
- Whistling around the front side glass.
- Hardened rubber.
- Cracked rubber.
- Seal shrinkage.
- Visible gaps around the glass.
- Flattened sealing surfaces.
- Loose or displaced sections.
- Vent glass rattling when closed.
- Increased dust entering the cabin.
- Water staining around door trim.
- Poor vent-window closure.
- The glass needing extra pressure to seal correctly.
Why Replacement Matters:
Replacing a worn Vent Window Seal helps restore:
- Weather resistance.
- Reduced water ingress.
- Reduced wind noise.
- Correct vent-glass support.
- Reduced rattling.
- Improved cabin refinement.
- Protection of the door and interior.
- Proper appearance around the glass.
On an early Porsche Targa, good window sealing is particularly important because multiple separate seals work together around the removable roof and side-glass system.
