Mercedes-Benz 300D Front Left Door Seal

This URO door seal is a specific-fit replacement for the front left door on 1975-1976 Mercedes-Benz 300D models. Built from EPDM rubber with an OE-style profile, URO 1157200778 helps restore a tight door-to-body seal and reduce wind noise, water intrusion, and debris entry.

Key Features

  • Specific fit for the front left door on 1975-1976 Mercedes-Benz 300D
  • EPDM rubber construction resists heat, UV exposure, water, and airborne debris
  • OE-style seal profile helps minimize door squeaks and wind noise
  • Smooth sealing surface helps reduce sticking between the door and body
  • Black finish for a factory-style appearance
  • Clip attachment type for vehicle-specific installation

Detailed Description

URO 1157200778 is a body sealing component engineered for the front left position on Mercedes-Benz 300D applications from 1975 and 1976. The EPDM material is selected for long-term flexibility and resistance to environmental exposure, while the precise seal shape supports consistent contact along the door opening. For buyers searching for a 1975-1976 Mercedes-Benz 300D front left door seal or a URO 1157200778 replacement, this part addresses worn, hardened, or compressed original sealing material.

This part cross-references URO-000735 for the same application.

What It Helps Solve

  • Wind noise from a worn or flattened door seal
  • Water leaks at the front left door opening
  • Dust and airborne debris entering the cabin
  • Door squeaks caused by deteriorated sealing material
  • Sticking or drag between the door and body at the seal surface

Installation Notes and Tips

Verify the front left position before installation and compare the new seal to the original profile and clip locations. Clean the door and body sealing surfaces thoroughly before fitting the replacement to help ensure proper seating and contact. Confirm that the seal is routed evenly around the opening so the door closes smoothly without binding.

Quality Assurance

URO lists this door seal with a 24 Month Unlimited Mileage Warranty. The EPDM rubber construction is heat- and UV-resistant, supporting long-term service in demanding exterior conditions.
