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.

Corteco 01033808B Differential Shaft Seal – 40x55x8/13mm

The Corteco 01033808B is a precision shaft seal designed for differential applications. Featuring an alternating-twist swirl lip, it ensures positive sealing at differential output shafts under varying rotational directions.

Key Specifications

Brand: Corteco | Part Number: 01033808B | EAN: 3358960203007 | Inner Diameter: 40 mm | Outer Diameter: 55 mm | Height 1: 8 mm | Height 2: 13 mm | Swirl Type: Alternating Twist

Is this a genuine Corteco seal?

Yes. Corteco is an OEM-grade sealing supplier and 01033808B meets original factory specifications.

What is the alternating twist lip?

An alternating-twist lip pumps oil back toward the gearbox regardless of shaft rotation direction, making it ideal for differential output shafts that may rotate in either direction.

Can I reuse this seal after removal?

No. Always fit a new seal — the lip takes a set in service and reuse causes leaks.

Why Choose Eco Torque?

As specialists in gearbox rebuilds and repairs, Eco Torque takes pride in offering genuine gearbox parts, high-quality aftermarket alternatives and competitive pricing.
