The NATIONAL 3.1875x4.500x0.500 M/L Leather Oil Seal is a high-quality heavy-duty rotary shaft seal manufactured from genuine leather.
Natural leather absorbs lubricant and forms a self-lubricating film, making it highly effective in dusty and contaminated environments where standard rubber seals may wear prematurely.
This seal is commonly used in large gearboxes, industrial pumps, conveyors, crushers, and heavy-duty machinery.
