The AEROQUIP 1.250x1.690x0.313 M/L Leather Oil Seal is engineered for rotating equipment requiring traditional leather sealing technology and reliable long-term operation.

The M/L Profile utilizes a reinforced carbon steel outer case combined with a genuine leather sealing lip. This traditional seal construction has been widely used in industrial machinery, pumps, gearboxes, and agricultural equipment for decades due to its durability and ability to conform naturally to shaft surface irregularities. AEROQUIP M/L seals typically utilize a carbon steel case combined with a leather lip construction.

Unlike conventional rubber oil seals, leather absorbs lubricating oil and forms a natural lubricating film between the shaft and sealing lip. This helps reduce friction, minimize wear, and maintain sealing effectiveness over long operating periods. Leather sealing elements are valued for their natural flexibility, resilience, and ability to adapt to shaft surfaces.

Leather seals are particularly effective in dirty, dusty, and poorly lubricated environments because the leather absorbs retained fluids and continues to provide sealing performance where synthetic elastomers may wear more rapidly. They are commonly selected for vintage machinery restoration and industrial equipment originally designed with leather seals.

The reinforced steel case provides excellent dimensional stability and secure retention within the housing while supporting continuous-duty industrial operation.

With dimensions of 1.250 x 1.690 x 0.313 inch, this seal is commonly used in industrial pumps, small gearboxes, agricultural machinery, conveyor drives, compressors, and OEM equipment utilizing inch-size shaft systems.
