385-4572 and 365-4922 Duo Cone Seals are final drive sealing components designed for Caterpillar heavy-duty trucks. Their metal-to-metal facing structure works with rubber sealing elements to maintain an oil-tight seal during rotation, while helping prevent external contaminants from entering the final drive. This makes them suitable for demanding mining, quarry and heavy-earthmoving applications where reliable lubrication and component protection are essential.
