xGenuine Ferrari Engine Sealing Gasket 109724 - OEM O-Ring
The Genuine Ferrari Engine Sealing Gasket 109724 is a genuine Ferrari O-ring used across a remarkable range of classic Ferrari engines and gearboxes. This small sealing ring sits in oil-carrying joints — main shaft gears, gearbox oil pumps, and crankcase covers — keeping pressurised oil exactly where it belongs. It is a genuine Ferrari part, made to the original material and tolerance specification.
The 109724 appears in Ferrari parts diagrams for an unusually wide spread of models: the 348, 355, 456, 512 BB/BBi/TR/M, 550 Maranello, 575M, 599, 612 Scaglietti, F50, Mondial t, and Testarossa. In these applications it typically seals the junction between rotating shafts and their housings — for example the main shaft gears and the gearbox oil pump — where a continuous, heat-resistant seal is needed between mating metal surfaces under oil pressure.
An O-ring rarely fails dramatically; it deteriorates slowly. The classic symptom is a persistent oil weep or slow drip at the shaft housing or pump cover, often noticed as a wet patch on the gearbox casing or a drop in oil level between services. Heat cycling and age harden the rubber compound until it loses its ability to conform to the groove, at which point even a small leak can contaminate the clutch area or attract dust that accelerates wear on the seal surface.
This genuine Ferrari part uses the factory rubber compound and groove tolerance for the 109724 application, so it seats correctly the first time and seals reliably through repeated heat cycles. Unlike generic O-rings of approximately the right size, the genuine ring matches the original cross-section and compression behaviour — the two properties that determine whether an O-ring seals or weeps. Small dimensional differences in a generic ring are exactly what turn a rebuild into a return visit.
Fitting is a job for a qualified Ferrari technician, since the 109724 is typically replaced during gearbox or engine service when the relevant housing is already open. It is good practice to replace these rings whenever the cover is removed — a used O-ring that has taken a compression set should never be reused. Order from European Auto Spares for genuine OEM Ferrari sealing hardware with worldwide delivery. Every unit is supplied as a brand-new genuine part in factory packaging.

Why Choose European Auto Spares
Exact Groove Specification
An O-ring only seals when its cross-section matches the groove. The genuine 109724 is made to the factory dimension for these Ferrari housings — not an approximate size from a generic assortment box.
Oil-Resistant OEM Compound
Genuine rings use the factory rubber formulation, resistant to engine oil, heat, and the pressure cycling of a running gearbox. Cheap rings swell or harden and start weeping far sooner.
Prevent Costly Rework
A weeping O-ring means draining fluids and reopening a freshly serviced housing — often hours of labour. The genuine ring is cheap insurance against doing the job twice.
Catalogue-Verified Application
The 109724 is a single part number shared across dozens of Ferrari diagrams. We verify your VIN against the exact diagram position, so you receive the ring for the right location.
Global Express Delivery
We ship genuine OEM Ferrari sealing hardware worldwide with protective packaging, so small precision parts arrive clean, undamaged, and ready to fit.
Complete the Job
When servicing a Ferrari engine or gearbox, it pays to replace all related seals at the same time. See the Genuine Ferrari Engine Oil Filter 234742 and the Genuine Ferrari Engine Oil Cap 293205 for fresh oil system hardware, or the Genuine Ferrari Ball Joint 157630 if your service extends to the suspension.

Technician's Advisory: The 109724 is a single part number used in several different positions per car — the correct quantity and location depend on your exact model and gearbox, so always confirm with your complete VIN before ordering; our team verifies compatibility before dispatch. Replace the ring whenever the housing is opened, and never reuse a ring that has taken a compression set.

xFrequently Asked Questions
The 109724 is a genuine Ferrari O-ring (seal ring) used across many classic Ferrari engines and gearboxes. It seals oil-carrying joints such as the main shaft gears, the gearbox oil pump, and crankcase covers. Ferrari specifies this single part number in diagrams for the 348, 355, 456, 512 range, 550, 575, 599, 612, F50, Mondial t, and Testarossa.
The classic sign is a persistent oil weep at a shaft housing or pump cover, often seen as a wet patch on the gearbox casing or falling oil level between services. Heat and age harden the rubber until it stops conforming to its groove. Since the 109724 sits inside an opened housing, replace it during scheduled engine or gearbox service.
The 109724 is listed for a wide range of classic Ferraris, from the 348 and Mondial t through the 550, 575, 599, 612, and F50, but the exact diagram position varies by model and gearbox. Send us your complete VIN and our team will confirm the correct application and location for your car, since one part number covers several positions.
A generic O-ring may look similar, but its cross-section and compound determine whether it seals. Slightly wrong dimensions weep under oil pressure, and generic compounds swell or harden in hot running. A leaking ring means draining fluids and reopening a freshly serviced housing. The genuine 109724 matches the factory groove specification exactly, making it cheap insurance against a repeat strip-down.
This brand-new genuine Ferrari part ships in factory packaging and is covered against manufacturing defects, with your statutory consumer rights applying in the UAE. If the part arrives damaged or incorrect due to our error, we replace or refund it. Because the 109724 covers several diagram positions, we verify your VIN to avoid ordering the wrong ring.
