The Yanmar 24314-000200 is a genuine OEM O-ring identified in current parts references as O-RING, 4CP20.0. Current online parts sources consistently match this part number to a 4 mm cross-section x 20 mm inside diameter O-ring.
This is a small but important sealing part used in Yanmar engine systems where the correct size and material matter for leak prevention and proper service fit. Yanmar’s current genuine-parts guidance emphasizes using OEM parts built to the same standards as the original equipment.
Key Features
Genuine Yanmar OEM O-ring.
OEM part number: 24314-000200.
Current parts description: O-RING, 4CP20.0.
Supported size reference: 4 mm x 20 mm ID.
Engine Compatibility
Specific marine-engine family fitment was not confirmed from the strongest currently reviewed sources for this part number. Fitment should be verified by part number, installed O-ring dimensions, and the exact service location before ordering. One current industrial-parts reference ties this number to certain 4TNV98 engine applications, but that does not by itself confirm marine-series fitment.
Serial Number Fitment Notice
Fitment should be confirmed by engine model, serial number, and the existing O-ring dimensions. Matching by OEM part number 24314-000200 remains the safest method.
When This Part Needs Replacement
Replace the O-ring whenever it is flattened, brittle, cut, swollen, leaking, or removed during service in a location where Yanmar specifies replacement. Seal-condition guidance here is based on the function of an O-ring; the reviewed parts sources primarily confirm part identity rather than service intervals.
Installation Notes
Install only where 24314-000200 is specified. Confirm the old seal matches the required 4 mm x 20 mm ID size before installation, and inspect the sealing surfaces for damage or contamination during service.
Alternate / Superseded Part Numbers when applicable
No superseded OEM number was confirmed in the reviewed sources. The supported OEM number is 24314-000200.
Parts Desk Insight
Small sealing parts like this are easy to underestimate, but using the exact O-ring size matters. A wrong cross-section or ID can cause sealing problems even when the part looks close at a glance.
