URO 123 720 15 78 64 Door Seal Front Left Weatherstrip

The URO Parts 123 720 15 78 64 is a replacement front left door seal (weatherstrip) engineered to restore a proper weather-tight fit on the Mercedes-Benz W123 sedan. Over time, original rubber door seals crack, harden, and shrink, allowing wind noise, water intrusion, and dust to enter the cabin. This URO replacement seal is manufactured to match OEM specifications in shape and material, making it a cost-effective alternative to the original Mercedes-Benz part.

• Molded rubber construction designed to match original OEM profile
• Restores a proper door-to-body seal, reducing wind noise and water leaks
• Designed to install into existing door channels and clips without modification
• Manufactured to OEM specifications as a direct-fit replacement
