About 700429260000 - O-Ring
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
The current catalog does not publish verified dimensions for 700429260000. Do not infer a 260 mm inside diameter from the number. References 0019972348 and 0089977545 need application checks before being treated as interchangeable seals.
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- Superseded gasket numbers often reflect a material or thickness change, so mixed old and new gaskets on one joint should be avoided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
Technical Data Status
Published catalog details help identify this part, but they are not a controlled drawing for the item offered. Measurements that are not shown here still need confirmation before substitution or order.
- Confirm inside diameter, cross-section, material, and the fluid and temperature at the sealing position.
