The OE Match Front 1/4 Glass Vertical Seal is a premium-quality replacement weather seal designed to provide a secure seal between the front quarter (1/4) glass and the surrounding door frame on compatible classic Porsche models. Manufactured to OE specifications for fit, profile and durability, this vertical seal helps prevent the ingress of water, wind and dust while maintaining the original appearance and fitment of the vehicle's window assembly.
Fits:
- Porsche 356 1950-55
- Porsche 356A 1955-59
- Porsche 356B 1959-63
- Porsche 356C 1963-65
Diagram Ref No 3
Manufactured from high-quality EPDM rubber, the seal is engineered to resist UV exposure, ozone, moisture and extreme temperature changes without cracking, shrinking or losing flexibility. Precision-moulded to match the original factory profile, it provides direct OE-style installation and ensures the correct positioning of the front quarter glass while helping to minimise wind noise and vibration.
What This Product Does:
- Seals the front quarter (1/4) glass against the door frame.
- Prevents water, dust and dirt from entering the cabin.
- Reduces wind noise around the window.
- Helps support correct positioning of the quarter glass.
- Protects the interior from moisture ingress.
- Maintains the original appearance of the window assembly.
- Provides factory-style fitment and sealing performance.
- Forms an essential part of the vehicle's door and window sealing system.
Symptoms Of Wear Or Failure:
- Water leaks into the cabin.
- Increased wind noise while driving.
- Cracked, hardened or split rubber.
- Shrinking or distortion of the seal.
- Visible gaps around the quarter glass.
- Rattling or movement of the glass.
- Moisture entering the door cavity.
- Perished or flattened sealing surface.
- Interior dampness following rain or washing.
- Reduced appearance due to aged weather seals.
Why Replacement Matters:
- The front quarter glass seal is continually exposed to sunlight, rain, temperature fluctuations and repeated opening and closing of the door. Over time, the rubber can harden, crack or shrink, reducing its ability to maintain an effective seal around the glass.
- A deteriorated seal can allow water and dust to enter the cabin and door cavity, increasing the risk of corrosion, interior damage and unwanted wind noise. It may also reduce the stability of the quarter glass and detract from the appearance of a restored or well-maintained classic Porsche.
- Replacing a worn or damaged seal restores the original weather protection, reduces cabin noise and maintains the correct fit of the quarter glass. The OE Match Front 1/4 Glass Vertical Seal is manufactured to OE standards using premium-quality EPDM rubber, providing factory-style fitment, excellent weather resistance and long-lasting durability, making it the ideal choice for Porsche restoration, repair and preventative maintenance.

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.

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 Glass — Fit, Finish, Clarity
OEMatch Door Glass components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Door glass seals form a weatherproof barrier around each door window, reducing wind noise, preventing water ingress and protecting interior trim on Porsche models.
Available Types
- Full window run seals
- Outer door glass seals
- Window channel liners and edge trims
Understanding OEMatch Door Glass
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original door glass.
OE (Original Equipment) refers to parts matching original specifications for the door glass and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM door glass engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Door glass seals sit in channels and on runs that guide the glass and maintain a continuous seal between glass and door frame. When seals lose elasticity or distort, water and noise can enter and window movement may be impeded; choosing the correct profile helps retain function and appearance.
Benefits Include
- Restores watertight sealing to prevent moisture damage to carpets and electrics
- Reduces wind noise and vibration for a quieter cabin
- Ensures smooth window movement and protects glass edges from wear
Why Door Glass Wear and Fail
- UV and ozone exposure causing hardening or cracking
- Compression fatigue and loss of sealing elasticity
- Contamination or damage from debris and misaligned windows
The Importance of Replacing with OEMatch Door Glass
Prompt replacement of worn seals prevents water ingress that can damage trim, carpet and electronics and avoids corrosion to internal door structures. Correct seals help maintain climate control efficiency and window alignment on Porsche vehicles while limiting progressive wear to adjacent components.
Advantages
- Suitable for restorations and routine maintenance on Porsche models
- Made from durable rubber compounds resistant to UV and ozone
- Available in profiles that match original runs and channels to preserve function and finish
Support & Advice
Fitting can appear straightforward but may require specific procedures such as correct positioning, sealing detail and careful reassembly to avoid panel damage. If you lack the right tools or experience, or if the vehicle includes hidden fasteners or sensors, seek professional installation. Recheck fasteners and seal compression after initial use.
