Delivery and Shipping
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 Crankshaft Oil Seal 12019250B – 40x52x7mm (Timing End)
The Corteco 12019250B is a high-quality crankshaft oil seal for the timing end of the engine. Made from FPM (fluoride rubber) with a right-hand swirl design, it provides a reliable seal against oil loss at the timing cover. A leaking crankshaft seal causes oil to contaminate the timing belt or chain, leading to premature wear and potential engine damage if left unchecked.
Part Number: 12019250B (Corteco)
Specifications:
- Inner Diameter: 40 mm
- Outer Diameter: 52 mm
- Height: 7 mm
- Material: FPM (fluoride rubber)
- Fitting Position: Timing End
- Swirl Type: Right turn-direction
OE Cross References: 55186757 (FIAT/Alfa Romeo), 100CP5143, 1447221 (FBU5115), 5518675, 893177701
What causes a crankshaft seal to fail?
Oil seals degrade over time due to heat cycling, oil contamination and age. Symptoms include oil staining around the timing cover, oil on the belt/chain, or a burning oil smell from the engine bay.
Is the Corteco brand reliable?
Yes — Corteco is a Freudenberg Group brand and is widely recognised as OEM-quality. Their seals are used in original equipment fitment by many major manufacturers.
How do I confirm this is the right seal for my vehicle?
Match the dimensions (40x52x7mm) and fitting position (timing end). You can also send us your UK registration or VIN and we will confirm compatibility.
Do I need to drain the engine to replace this seal?
Not necessarily — however the timing cover must be accessed, which varies by vehicle. Professional fitment is recommended.
Does Eco Torque stock other Corteco seals?
Yes — we stock a range of Corteco shaft seals and gaskets across multiple dimensions. Browse our store or contact us with your requirements.
