Product Information

Front 1/4 window seal.
Rubber seal for vent window on Cabriolet models with Karmann Hardtop
Rubber sealing profile / gasket designed to fit around the vent (side) window of early-generation Porsche models. The profile forms a continuous seal between the vent glass and the car body/frame - preventing water, dust, wind and unwanted air from entering the cabin or interior spaces.

Fits:
Porsche 356 Cabrio 1.1L-2.0L 08/1952-12/1965

Diagram Ref no 21

This vent-window seal:
•  Creates a weather-proof barrier around the vent/side window, preventing water ingress, dust, and external debris.
•  Maintains a tight, durable seal that reduces wind-noise and vibrations when driving.
•  Protects interior trim and avoids leaks that could lead to moisture damage or rust - especially common in classic Porsches.
•  Restores original sealing performance when the old gasket has become hardened, cracked, or lost elasticity due to age and exposure.

Why replacement matters:
• Old seals often harden, crack or degrade over decades - causing leaks, drafts, noise, dust ingress, or water seepage into the cabin.
• A degraded seal cannot guarantee proper weatherproofing, which may lead to interior moisture damage, rust or trim deterioration.
• Replacing with a correct-spec sealing profile ensures the original cabin comfort, reduces wind-noise or rattling, and preserves the vehicle’s structural and cosmetic integrity.
