Frequently Asked Questions

What does a shaft seal do?

A rotary shaft seal (also known as an oil seal or lip seal) retains lubricant inside a rotating assembly such as a differential or gearbox while keeping out dirt and contamination. A worn or leaking seal will cause fluid loss and potential damage to the assembly.

How do I know this seal is correct for my vehicle?

Match the inner diameter (44mm), outer diameter (78.1mm), and width (10mm) to your existing seal. If in doubt, contact us with your UK registration number or VIN and we will confirm the correct part.

Is Corteco a quality brand?

Yes, Corteco (part of the Freudenberg Group) is a globally recognised OE and aftermarket supplier of seals, gaskets, and vibration control products for the automotive industry.

Do I need to drain the gearbox to replace a shaft seal?

In most cases, yes. Replacing a shaft seal typically requires draining the relevant fluid and removing any associated components. Professional installation is recommended.

This seal is supplied new by Corteco. Contact us for specific warranty information if required.
