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.

The OE Match Front Quarter Window Seal is a premium-quality replacement weather seal designed to provide a secure, weatherproof seal around the front quarter window on compatible classic Porsche models. Manufactured to OE specifications for fit, profile and durability, these seals restore the original fitment of the fixed quarter glass while protecting the cabin from water, wind and road contaminants.
Fits:
- Porsche 356 1950-55
- Porsche 356A 1955-59
- Porsche 356B 1959-63
- Porsche 356C 1963-65

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.

OEMatch Door Seals — Fit, Function, Confidence
Door seals preserve cabin comfort and protect interior trim by keeping out water, wind and dust while reducing wind noise and vibration. For Porsche models, correct sealing supports climate control, minimises corrosion risk and helps maintain the vehicle’s condition during restoration or regular ownership.
Available Types
- Door frame seals
- Door jamb and hinge seals
- Window run and channel seals
- Corner and flexible sealing sections
Understanding OEMatch Door Seals
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original door seals. OE (Original Equipment) refers to parts matching original specifications for the door seals and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM door seals engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch provides a wide selection of parts and sealing solutions for Porsche applications, with an extensive catalogue of part numbers and cross-references drawn from OE data. Products are offered for both classic and modern models and are developed to assist with restorations, maintenance and routine renewal of weatherseals.
Benefits Include
- Restores airtight and watertight sealing to prevent leaks and ingress
- Reduces wind noise and vibration for a quieter cabin
- Protects interior panels and trim from moisture-related damage
Why Door Seals Wear and Fail
- Exposure to UV and ozone causing cracking, hardening or shrinkage
- Loss of compression and elasticity through age and repeated use
- Contamination from dirt, oil or road debris and misaligned doors causing tearing
- Prolonged moisture retention leading to mould or corrosion around frames
The Importance of Replacing with OEMatch Door Seals
Replacing worn or damaged seals restores the vehicle’s weather protection and acoustic performance. Proper seals reduce the risk of water ingress and subsequent corrosion, help maintain interior condition and support effective heating and cooling. Selecting the right compound and profile for the model reduces repeat interventions and preserves value.
Advantages
- Available in EPDM and neoprene compounds chosen for flexibility and weather resistance
- Direct-fit replacements engineered to match original dimensions and tolerances
- Coverage for both classic restorations and modern Porsche models
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. Protect paintwork during removal and fitting, confirm correct alignment before trimming or bonding, and recheck fixings after initial use.
