The TROSTEL Oil Seal 0.625x1.375x0.250 M/L LEATHER is engineered for rotary shaft applications requiring a durable sealing solution for industrial machinery, legacy equipment, agricultural systems, gearboxes, pumps, and mechanical power transmission equipment.

The M/L Profile combines a reinforced metal outer case with an oil-treated leather sealing lip. The metal case provides structural strength, dimensional stability, and secure installation in the housing, while the leather lip maintains contact with the rotating shaft to retain lubricant inside the equipment.

Leather sealing elements are well suited to machinery operating at low to moderate shaft speeds, especially where the shaft surface may be slightly worn, irregular, or less finely finished than required for modern elastomer seals. The leather lip can absorb a small amount of lubricant, helping maintain lubrication at the sealing contact area and reducing dry friction during operation.

Manufactured from selected industrial leather, this seal is suitable for use with:

Mineral oils

Gear oils

Bearing lubricants

Industrial lubricating oils

Petroleum-based lubricants

Grease-lubricated systems where application-compatible

The leather construction also provides useful resistance to dust and abrasive contamination in older or heavy-duty equipment. However, installation dimensions, shaft condition, lubricant compatibility, rotational speed, and operating temperature should always be confirmed before replacement.

With dimensions of 0.625 × 1.375 × 0.250 inch, this TROSTEL leather oil seal is commonly used in compact gearboxes, small industrial pumps, agricultural machinery, bearing housings, conveyor drives, vintage machinery, and OEM equipment using inch-size shafts.
