The AEROQUIP Oil Seal 1.000x1.832x0.500 M/L/L Leather is designed for industrial rotary shaft applications requiring lubricant retention around a 1.000-inch shaft.

Installed between the rotating shaft and stationary housing, the leather sealing element creates controlled radial contact with the shaft surface. The oil-treated leather adapts to minor shaft irregularities and can provide effective sealing in machinery originally designed for leather-type shaft seals.

The product is identified by the AEROQUIP manufacturer designation M/L/L. This is a manufacturer-specific profile code and should not be interpreted solely from the letters. The exact cross-section, number and arrangement of leather elements, metal-support geometry, lip orientation, outside-case construction, installation direction, and any internal retaining components must be verified against the original seal or technical drawing.

Industrial leather seals are commonly selected for:

• Mineral oils
• Gear oils
• Bearing grease
• Petroleum-based lubricants
• Slow-to-moderate shaft speeds
• Older or specialized industrial machinery

Leather can conform well to slightly worn shaft surfaces and may perform reliably in equipment originally designed for leather seals. However, performance depends strongly on leather grade, oil treatment, lubrication, shaft finish, temperature, rotational speed, housing alignment, and installation method.

Leather generally requires adequate lubrication and should not be operated dry. Compatibility must also be verified for synthetic lubricants, water-rich environments, aggressive chemicals, and elevated temperatures.

The inch dimensions correspond approximately to:

Shaft diameter: 1.000 inch or 25.40 mm

Housing diameter: 1.832 inches or 46.53 mm

Seal width: 0.500 inch or 12.70 mm

The relatively substantial 0.500-inch axial width suggests a specialized metal-supported leather sealing assembly. Accurate dimensional measurement and verification of the original M/L/L cross-section are essential before replacement.

🔁 Equivalent

Suitable replacement for compatible:

• AEROQUIP M/L/L Leather Shaft Seal
• AEROQUIP 1.000x1.832x0.500 Seal
• 25.40x46.53x12.70 Leather Seal
