The TROSTEL 2.688x3.875x0.469 M/L Leather Oil Seal is engineered for rotating equipment requiring durable sealing performance and traditional leather sealing technology.

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

Unlike synthetic rubber seals, genuine leather absorbs lubricating oil and creates a natural lubricating film between the shaft and sealing lip. This unique characteristic helps reduce friction, minimize wear, and maintain effective sealing performance over extended operating periods.

Leather oil seals are particularly suitable for machinery originally designed with leather sealing technology. They perform exceptionally well in dusty, dirty, and poorly lubricated environments where conventional elastomer seals may experience accelerated wear.

The reinforced steel case provides excellent dimensional stability, vibration resistance, and secure housing retention. Combined with the flexibility and durability of genuine leather, this seal delivers dependable performance in demanding industrial applications.

With dimensions of 2.688 x 3.875 x 0.469 inch, this seal is commonly used in industrial gearboxes, pumps, agricultural machinery, compressors, conveyor drives, and OEM equipment utilizing inch-size shaft systems.
