Elring 321-501-641 Front Wheel Grease Seal for Disc Brakes

The Elring 321-501-641 is a precision-engineered front wheel grease seal designed specifically for vehicles equipped with disc brake systems. This critical seal installs into the disc brake rotor after the inner race and bearing are installed, creating a protective barrier that keeps bearing grease contained while preventing dirt, water, and debris from entering the wheel bearing assembly and axle.

Key Features:

• Manufactured by Elring, an OEM supplier with over 120 years of sealing expertise
• Constructed from durable NBR (nitrile butadiene rubber) for excellent oil and heat resistance
• Dimensions: 40mm x 52mm x 7.5mm - thinner profile specifically designed for disc brake applications
• Precision-manufactured to meet strict OEM tolerances for proper fit and sealing performance
• Must be pressed evenly into rotors for proper installation

This seal is essential maintenance when servicing front wheel bearings on disc brake-equipped vehicles. Elring's reputation as a trusted OEM gasket and seal manufacturer for major automotive manufacturers ensures reliable performance and longevity. The seal's specialized thickness is engineered to work correctly with disc brake rotor spacing, making it the proper replacement for disc brake conversions and factory disc brake systems.
