Durable Polyacrylate Construction and Design Features

The National 6712NA wheel seal is constructed from polyacrylate, a material known for its resistance to heat, oil, and wear. The clockwise-spiral lip design improves sealing efficiency by directing contaminants away from the shaft, reducing the risk of leaks. The Redicoat treatment further enhances corrosion resistance, extending the service life of the seal. With precise dimensions including a 1.875-inch shaft diameter and a 2.762-inch outside diameter, this seal fits securely within the housing bore of 2.758 inches, ensuring a tight and reliable fit.
