Cometic C15221 Ford Differential Cover Gasket AFM - 10.5 12-Bolt 032

Cometic C15221 Ford 10.5" Differential Cover Gasket

The Cometic C15221 is a precision-engineered differential cover gasket designed specifically for Ford 10.5-inch rear differentials with 12-bolt cover patterns. This high-performance gasket ensures a reliable seal between the differential housing and cover, preventing fluid leaks and maintaining proper lubrication of internal components.

Key Features

• AFM Construction: Built with Advanced Fiber Material (AFM) technology for superior sealing performance and durability
• Precise Thickness: Manufactured at .032 inches (0.8mm) for optimal compression and sealing
• 12-Bolt Pattern: Designed to match the factory bolt pattern on Ford 10.5" rear differentials
• Heat and Chemical Resistant: Withstands extreme temperatures and exposure to gear oils and differential fluids
• Reusable Design: AFM material allows for multiple installations when properly handled
• OE Quality: Meets or exceeds original equipment specifications for fit and performance

About AFM Technology

Cometic's Advanced Fiber Material (AFM) gaskets feature a composite construction that combines the benefits of multi-layer steel gaskets with fiber-based materials. This technology provides excellent torque retention, superior resistance to blowout, and maintains an effective seal even under extreme operating conditions. AFM gaskets are designed to handle the thermal cycling and pressure changes common in differential applications.

Applications

This gasket is engineered for Ford 10.5-inch ring gear rear differentials with 12-bolt cover configurations. The 10.5" differential is commonly found in Ford Super Duty trucks and other heavy-duty applications requiring robust axle components.

Installation Notes

Clean all mating surfaces thoroughly and remove old gasket material before installation. Follow manufacturer torque specifications for differential cover bolts and use a proper torque sequence (star pattern) to ensure even compression. Allow proper cure time before refilling with differential fluid.
