The AEROQUIP Oil Seal 2.688x3.548x0.500 M/F Fabric is designed for industrial rotating equipment requiring durable construction, reliable lubricant retention, and resistance to mechanical wear.

The manufacturer-specific M/F Profile is associated with a composite seal construction using industrial fabric sealing material and metal reinforcement. The metal component helps maintain dimensional stability and supports secure installation within the housing, while the fabric-based sealing element creates controlled contact around the rotating shaft.

Fabric seals are often selected for demanding industrial applications where structural strength, resistance to deformation, and compatibility with older machinery designs are important. Depending on the original construction, the fabric material may be impregnated or treated to improve resistance to oil, grease, abrasion, and environmental contamination.

Because M/F profile codes are manufacturer-specific, the exact arrangement of the metal case, fabric sealing element, internal reinforcement, lip geometry, and installation direction should be compared with the original seal or technical drawing before replacement.

This seal is generally suitable for compatible applications involving:

• Mineral oils
• Gear oils
• Bearing grease
• Industrial lubricating oils
• Petroleum-based lubricants
• Compatible grease-lubricated systems

The performance of a fabric seal depends on the fabric composition, impregnation treatment, lubricant type, shaft speed, temperature, shaft condition, moisture exposure, and operating environment. These factors should be verified before installation.

The inch dimensions correspond approximately to:

Shaft diameter: 2.688 inches or 68.28 mm

Housing diameter: 3.548 inches or 90.12 mm

Seal width: 0.500 inch or 12.70 mm

The specific shaft and housing dimensions indicate that this seal may be intended for a dedicated bearing housing, gearbox, pump, transmission, axle assembly, or OEM industrial machine. Accurate dimensional measurement and M/F profile verification are essential before replacement.

🔁 Equivalent

Suitable replacement for compatible:

• AEROQUIP M/F Fabric Rotary Shaft Seal
• 2.688x3.548x0.500 Fabric Oil Seal
• 68.28x90.12x12.70 Rotary Seal
• Industrial Fabric Oil Seal
