Looking for a straightforward way to solve a common challenge? This video explores how to restore a tight, quiet excavator cab by replacing the door rubber sealing strip on LG55, LG60, LG65, LG75, LG80, LG90, and LG135 models. Watch a step-by-step demonstration of the snap-in installation, see how the hollow elastic structure compresses and rebounds, and learn how it blocks rainwater, dust, and noise while reducing door rattle. We also compare old, hardened strips with the new UV-resistant, ozone-resistant rubber and show the difference in fit and sealing performance. Ideal for B2B buyers sourcing practical aftermarket cabin parts.
