The REPCO 4.500x5.505x0.563 M/L LEATHER Oil Seal is engineered for demanding rotary shaft applications where leather sealing technology provides superior durability compared with conventional elastomer seals. It is widely installed in industrial gearboxes, heavy-duty pumps, mining machinery, steel processing equipment, paper mills, agricultural machinery, construction equipment, and OEM industrial machinery.

The M/L Profile utilizes a reinforced steel outer case combined with a genuine oil-treated leather sealing lip. Leather sealing elements provide excellent abrasion resistance and perform exceptionally well on shafts with slightly rough surfaces, making them ideal for older industrial machinery and heavy-duty equipment operating in dusty or contaminated environments.

Unlike synthetic rubber seals, the leather lip naturally absorbs lubricating oil during operation, maintaining a lubricated sealing surface that minimizes friction, reduces shaft wear, and extends seal life.

Manufactured from premium oil-treated industrial leather, this seal is compatible with:

• Mineral oils
• Gear oils
• Bearing lubricants
• Industrial lubricating oils
• Petroleum-based lubricants

With dimensions of 4.500 × 5.505 × 0.563 inch, this oil seal is commonly used in industrial gearboxes, heavy-duty pumps, mining equipment, steel mills, conveyor drives, paper mills, agricultural machinery, and OEM rotating equipment utilizing inch-size shaft systems.
