Convertible Top Seal for Mercedes-Benz SL

This URO convertible / hard top seal restores the sealing surface at the top of the door window on compatible Mercedes-Benz SL soft tops. It is built to replace hardened or cracked rubber that can let in water, dust, and wind noise.

  • Guaranteed fitment for the listed applications
  • OE-style seal profile helps reduce wind noise and convertible top squeaks
  • EPDM rubber resists UV exposure and stays pliable longer
  • Smooth sealing surface helps reduce sticking between the top and body
  • Direct replacement for the left side top-of-door-window seal

Detailed Product Overview

URO part number 1077200978 is a body sealing component for the left side of the soft top window opening. It is compatible with 1981-1985 Mercedes-Benz 380SL, left, top of door window on soft top, and 1986-1989 Mercedes-Benz 560SL, left, top of door window on soft top. For owners searching for a Mercedes-Benz 380SL left soft top window seal or a Mercedes-Benz 560SL convertible top seal, 1077200978 provides the correct OE-style profile for a direct replacement.

The EPDM rubber construction is made to hold its shape and seal out moisture and airborne debris while maintaining smooth contact with the convertible top and body. This helps address common aging issues on classic SL models where original rubber becomes brittle, shrinks, or cracks. This part cross-references 107 720 0978-A and URO-000378 for the same application.

Common Issues This Seal Can Address

  • Water intrusion at the top of the door window
  • Wind noise around the soft top edge
  • Convertible top squeaks caused by worn sealing surfaces
  • Dust entering the cabin through aged rubber
  • Sticking or drag between the convertible top and body

Installation Notes

Verify left-side placement before installation and compare the new seal to the original profile. Clean the mounting surface thoroughly so the seal seats evenly and maintains full contact along the window opening. Proper alignment is important on 1981-1985 Mercedes-Benz 380SL and 1986-1989 Mercedes-Benz 560SL soft top applications.

Quality Assurance

URO backs this seal with a 24 Month Unlimited Mileage Warranty.
