0002040479 Specification
About 0002040479 - Cup Seal
Gaskets and seals are application-specific — material grade, thickness, and shape all vary by engine installation. We confirm part number against engine series and recommend full gasket kits for overhaul projects.
Technical Notes: Gaskets and seals
Gaskets, O-rings, and sealing rings keep oil, coolant, fuel, charge air, and exhaust gas in their own circuits. On high-speed MTU engines they work against high combustion pressures and frequent thermal cycling, so a seal that looks intact can still have lost its elasticity or set to the shape of the old joint.
When This Type of Part Is Usually Replaced
- a joint has been opened for inspection or repair, even if the old seal looks usable
- oil or coolant weeping appears at a cover, pipe flange, or housing
- a coolant test shows oil contamination or combustion gas in the cooling system
Checks Before Ordering
- Material matters: fuel-system and coolant-system O-rings of the same size can use different elastomers
- Superseded gasket numbers often reflect a material or thickness change, so mixed old and new gaskets on one joint should be avoided
- Order the complete set for a joint rather than single pieces when the cover or head comes off
