Manufactured from high-quality automotive-grade EPDM rubber, the plug is engineered to resist moisture, UV exposure, ozone, temperature extremes and continual vibration without hardening, shrinking or cracking. Precision-moulded to fit 20mm diameter apertures, it provides direct OE-style installation, making it ideal for replacing missing, damaged or deteriorated body plugs during restoration, accident repair or routine maintenance.

What This Product Does:

• Seals 20mm factory access holes within the door assembly.
• Prevents the ingress of water, dust and road debris.
• Helps protect the inside of the door from corrosion.
• Reduces the risk of moisture entering the door cavity.
• Maintains the original appearance of the bodywork.
• Provides a secure, vibration-resistant fit.
• Restores factory sealing performance.
• Forms an essential part of the vehicle's body sealing system.

Symptoms Of Wear Or Failure:

• Missing rubber plug.
• Cracked, hardened or split rubber.
• Loose-fitting or partially dislodged plug.
• Water entering the door cavity.
• Increased dirt or debris inside the door.
• Corrosion developing around exposed access holes.
• Wind noise caused by unsealed openings.
• Moisture-related damage within the door.
• Visible deterioration due to age or UV exposure.
• Untidy appearance of the door assembly.

Why Replacement Matters:

• 
  
• Door sealing plugs are continually exposed to water, road salt, dirt, vibration and changing temperatures. Over time, the rubber can harden, shrink or crack, reducing its ability to provide an effective seal. Missing or damaged plugs leave factory access holes exposed, allowing contaminants and moisture to enter the door cavity.
• Water ingress can accelerate internal corrosion, damage door components and contribute to rattles, unwanted noise and premature deterioration of electrical and mechanical parts inside the door. Replacing damaged or missing plugs is a simple yet effective way to protect the vehicle's body structure and preserve its long-term condition.
• Replacing the original component with the OE Match Door Round Rubber Plug restores the integrity of the door sealing system. Manufactured to OE standards using premium automotive-grade EPDM rubber, it provides factory-style fitment, excellent weather resistance and long-lasting durability, helping protect your Porsche against corrosion while maintaining its original finish and build quality.
