Information
Front 1/4 light window lower seal.
Replacement rubber seal for the small vent (quarter-light) windows or fixed vent-glass on classic Porsche 911/912/964 models. It is moulded to match the original seal’s profile, length ensuring proper fitment in the door-frame groove and restoring the original sealing integrity.
Fits
Porsche 911 1964 - 1973 for the vent windows (both sides)
Porsche 911 / T 1974 - 1989 for the outside of the door (both sides)
Porsche 964 1989 - 1994 (both sides)
Diagram ref no. 11
This window seal creates a tight, weather-proof barrier around the vent or quarter-light glass, preventing water, dust, and wind from entering the cabin. It reduces wind-noise and drafts for improved comfort, while maintaining correct glass seating and alignment for a clean, factory-original appearance. The seal also cushions the glass, protecting both the door frame and the glass edge from vibration and wear over time.
Seals degrade over time - rubber can harden, shrink, or crack due to age, UV exposure, and repeated flexing. When the seal fails:
• Water can leak into the cabin, causing wet carpets or interior corrosion.
• Dust, wind-noise, and drafts may enter the cabin, creating discomfort.
• Glass alignment may become poor, leading to gaps or rattles.
• Corrosion risk increases as moisture collects behind the door trim.
Replacing with a fresh seal restores proper weather-proofing, cabin comfort, and preserves body integrity, especially important on classic 911s used in everyday or show car condition.
You should replace this seal if the original rubber has become brittle, cracked, deformed, or is missing altogether. A new seal is also recommended if you notice water leaks, dust entering through the vent window area, or increased wind-noise or rattling at speed. If the vent glass no longer sits evenly or you are carrying out a restoration or refreshing the door trim and glass assembly, installing a fresh seal will help ensure proper fit and weather protection.
