The REPCO Oil Seal 3.188x4.250x0.625 M/L LEATHER is a premium industrial rotary shaft seal specifically engineered for heavy-duty applications requiring reliable sealing performance and resistance to harsh environmental conditions.

The M/L construction consists of a carbon steel outer case combined with a genuine leather sealing lip. Leather sealing technology has been used for decades in industrial machinery because the leather lip naturally absorbs lubricant and forms a thin lubrication film between the shaft and seal contact surface. This helps reduce friction, minimize shaft wear, and maintain sealing effectiveness even in dusty operating environments.

Unlike standard rubber oil seals, genuine leather seals offer excellent performance in applications where contamination, vibration, and shaft surface imperfections are common. The leather lip adapts well to shaft irregularities and provides dependable sealing for older machinery and equipment originally designed with leather seals.

With dimensions of 3.188 x 4.250 x 0.625 inch, this seal is commonly used in industrial gearboxes, pumps, conveyors, agricultural machinery, mining equipment, and imported machinery utilizing inch-size sealing systems.
