The REPCO 4.000x4.750x0.375 M/L Leather Oil Seal is engineered for industrial rotating equipment requiring durable sealing performance and traditional leather sealing technology.

The M/L Profile consists of a reinforced carbon steel outer case combined with a genuine leather sealing lip. This proven sealing design has been widely used in industrial machinery, agricultural equipment, pumps, compressors, and power transmission systems for decades because of its excellent shaft conformability and durability.

Unlike conventional synthetic rubber oil seals, genuine leather absorbs lubricating oil and creates a natural lubrication film between the sealing lip and shaft surface. This self-lubricating characteristic helps reduce friction, minimize wear, and maintain sealing efficiency during extended operating periods. Leather sealing technology remains highly valued in machinery restoration and heavy-duty industrial applications.

The steel case provides structural rigidity and secure housing retention while the leather sealing lip maintains effective lubricant retention and contamination protection. Leather seals are particularly suitable for machinery originally designed with leather sealing technology and for applications where shaft surfaces may have minor wear patterns.

With dimensions of 4.000 x 4.750 x 0.375 inch, this seal is commonly used in industrial pumps, gearboxes, agricultural machinery, compressors, mining equipment, conveyor drives, heavy industrial machinery, and OEM equipment utilizing inch-size shaft systems.
