Volvo Penta 20939274 is a genuine OEM O-ring used in Volvo Penta engine-system applications. Volvo Penta's official parts catalog identifies part 20939274 simply as "O-ring," and current catalog references place it in Volvo Penta fuel injector assemblies rather than as a universal sealing ring.
Key Features
Genuine Volvo Penta OEM part number 20939274. Official Volvo Penta description: O-ring. Current Volvo Penta parts-section references show it in a fuel injector diagram, and aftermarket OEM references also associate it with DPI-A / Cables and Fuses catalog placement, which reinforces that fitment should be confirmed by the exact assembly and serial-numbered application.
Engine Compatibility
Current Volvo Penta catalog coverage directly places 20939274 in a fuel injector part section that fits TAD761VE, TAD762VE, TAD763VE, TAD764VE, and TAD765VE. Additional catalog references place the same part number in other Volvo Penta assembly views, so fitment should be treated as engine-, assembly-, and serial-specific rather than assumed across all Volvo Penta models.
Serial Number Fitment Notice
Always confirm 20939274 against the exact engine serial number and the correct Volvo Penta parts diagram before ordering. Volvo Penta's parts shop specifically instructs users to identify the exact engine, shield, or drive when locating spare parts, which is especially important for small sealing parts used in multiple assemblies.
When This Part Needs Replacement
Replace this O-ring when the original seal is flattened, cut, hardened, swollen, leaking, or removed during service and no longer suitable for reliable reuse. On injector and similar sealing points, renewing the O-ring during reassembly helps reduce fuel, oil, or air leaks and helps maintain proper sealing performance. This service guidance is an application-based inference from the identified fuel-injector usage.
Installation Notes
Install only in the correct matched Volvo Penta application. Clean the sealing surfaces, inspect the groove and mating component for wear or contamination, and use the correct Volvo Penta service information for the serial-numbered engine before reassembly. Because this is a small seal used in critical engine assemblies, confirming the exact diagram location before installation is the safest approach.
Alternate/Superseded Part Numbers
Current references reviewed list this part under Volvo Penta number 20939274, and multiple sources also associate it with replacement or OE-linked number 60115626. That cross-reference should still be verified against the exact serial-numbered application before use.
Parts Desk Insight
Small O-rings like 20939274 are inexpensive, but they often seal some of the most important connections on the engine. Replacing the seal anytime the joint is opened is usually cheap insurance against leaks, repeat labor, and hard-to-trace performance issues after service. The identified injector-related application makes correct fit and condition especially important.
