The TROSTEL 2.375x3.486x0.6875 M/L/L Leather Oil Seal is engineered for industrial rotating equipment requiring durable sealing performance and traditional leather seal construction.

The M/L/L Profile utilizes a reinforced carbon steel outer case combined with a genuine leather sealing lip. This traditional design has been widely used in industrial machinery, pumps, gearboxes, agricultural equipment, and heavy rotating systems for decades because of its ability to adapt naturally to shaft surface imperfections while maintaining reliable sealing performance.

Unlike conventional rubber oil seals, genuine leather absorbs lubricating oil and creates a natural lubricating film between the shaft and sealing lip. This characteristic helps reduce friction, minimize wear, and maintain sealing efficiency over extended operating periods. Leather seals remain a preferred solution for restoration projects and machinery originally designed with leather sealing technology.

The leather sealing element performs exceptionally well in dusty, dirty, and poorly lubricated environments because the material retains lubricant within its structure while maintaining effective sealing performance. This makes leather seals particularly suitable for agricultural machinery, mining equipment, heavy industrial machinery, and legacy equipment operating under harsh conditions.

The reinforced steel case provides excellent dimensional stability, vibration resistance, and secure housing retention during continuous-duty operation. Combined with the flexibility and durability of genuine leather, this seal offers dependable long-term service life.

With dimensions of 2.375 x 3.486 x 0.6875 inch, this seal is commonly used in industrial gearboxes, heavy-duty pumps, agricultural machinery, conveyor drives, compressors, and OEM equipment utilizing inch-size shaft systems.
