Delivery and Shipping

UK delivery — parts we hold in stock

Ordered before 2pm on a working day, these are dispatched the same day by express courier and normally arrive within 1–2 working days.

Parts supplied from our European supplier

A large part of our range is held by our supplier in Germany rather than on our own shelves. We order these in for you as soon as you place the order. They normally dispatch within 7–10 working days, and are then sent on by express courier like anything else. Nothing ships to you direct from Germany — it comes to our Arlesey workshop first, so you deal only with us for returns and warranty.

Collection from Arlesey

Click and collect is available on parts we physically hold. If an item has to come in from our supplier it cannot be collected, and checkout will tell you so before you pay.

International

3–5 working days once dispatched. Any customs charges or excise duties are the responsibility of the buyer.

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.

Does this seal come with a warranty?

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