The TROSTEL 1.375x3.355x0.469 M/L LEATHER Oil Seal is engineered for industrial applications where conventional rubber oil seals may not provide sufficient durability in dusty, abrasive, or contaminated operating conditions.

The M/L Profile combines a robust metal outer case with a genuine leather sealing lip. This design ensures secure housing retention while allowing the leather lip to conform naturally to shaft surfaces, maintaining effective sealing performance over extended operating periods.

Unlike standard elastomer seals, the genuine leather lip absorbs lubricant and continuously forms a natural lubrication film between the shaft and sealing surface. This reduces friction, minimizes shaft wear, improves sealing efficiency, and provides outstanding performance in environments exposed to dust, dirt, sand, and abrasive particles.

The heavy-duty construction makes this seal particularly suitable for industrial pumps, agricultural equipment, mining machinery, conveyor systems, crushers, gear drives, and older imported machinery where leather oil seals remain the preferred sealing solution.

With dimensions of 1.375 x 3.355 x 0.469 inch, this seal is commonly used in heavy industrial applications requiring reliable sealing performance and superior contamination resistance.
