Information
Rear 1/4 window seal (inner).
The rear quarter window seal sits around the rear side window (quarter glass) opening, creating a weather-tight barrier between the glass and the vehicle body. Its role is to block water, wind, dust, and external noise from entering the cabin, helping preserve a dry, quiet, and comfortable interior.
Sold each. Fits Left or Right side.
Fits:
Porsche 356 Pré-A 1951 - 1955 Coupe * with chassis no from: F 10 531 >>

Porsche 356B / 356C 1960-63 Coupe -REUTTER-
Diagram ref no 17
This seal provides a secure and flexible interface between the fixed rear quarter glass and the body panel. It supports the glass, cushions vibrations, and ensures a snug fit by preventing gaps that can lead to leaks or noise.
• Application: Rear quarter (D-window) weatherseal — fits around the quarter window frame on the coupe body. Can be used on either side as specified by fitment guide.
Over time, original quarter window seals can harden, shrink, crack, or deteriorate due to age, heat, UV exposure, and repeated vibration. When seals fail:
• Water can seep into the cabin during rain or car washes.
• Wind and road noise can increase at speed.
• Rust and interior damage may develop from moisture ingress.
Replacing worn seals restores the original weatherproofing and comfort levels, helping preserve the condition and value of your classic Porsche.
Replace the rear quarter window seal if you notice:
• Water entering around the rear window area
• Excessive wind noise or rattling while driving
• Hard, cracked, or visibly deformed seal material
• Loose fitment or gaps between glass and body
• During a comprehensive weatherseal refresh or restoration

Information
Rear 1/4 window seal (inner). Seal is applied to the body where window opens.
The quarter window seal act as weather seals and vibration buffers for the rear side (quarter) windows. They prevent water, wind, and dust ingress around the moving glass edges while the vehicle is in motion and provide a secure, low-noise interface between the window glass and the body. Proper sealing also supports climate control efficiency and reduces road noise entering the cabin.
Fits:
Porsche 356 / 356A 1950 - 1959 COUPE
Porsche 356B / 356C 1960 - 1963 COUPE
Diagram ref no 15
• Application: Quarter window (side glass) seal on the left side (OE ref no 64454390300) and right side (OE ref no 64454390400) of the body. Designed to match original Porsche OEM specifications for correct fit and sealing performance.
Installed along the rear quarter window frame on each side of the coupe, these seals ensure the glass sits snugly against the body without gaps or excessive play. They help maintain the structural integrity of the window assembly and contribute to a quiet, sealed interior environment.
Original quarter window seals can harden, shrink, crack, or detach due to age, heat cycles, and exposure to environmental elements. When they fail:
• Water can seep into the cabin, leading to damp carpets and interior damage.
• Wind noise and buffeting can increase, especially at highway speeds.
• Road dust and exhaust fumes may enter the passenger compartment.
Replacing worn seals restores proper weather sealing, preserves original fit and finish, and helps protect the interior and bodywork of your classic Porsche.
Replace the quarter window seals if you notice:
• Water dripping into the cabin near the rear side windows
• Excessive wind or road noise at speed
• Visible cracks, shrinkage, or gaps in the existing seals
• Loose or detached sealing bead along the window edge
• During a full weatherseal or body restoration project
