This sealing brush is supplied as a strip 880 mm long, intended to be cut to the required length during installation. It functions as a flexible barrier, closing the gap between moving and stationary surfaces on the harvesting machine to contain crop material and dust. A worn or compressed brush allows debris to pass through, reducing sealing effectiveness and potentially leading to contamination of downstream components. The brush is installed by trimming it to match the mounting channel length and securing it in place; no gasket or sealant is required for the brush itself.
