Volvo Penta 20579690 is a genuine OEM sealing component listed by Volvo Penta as a gasket or sealing ring, depending on catalog view. Current parts references consistently place this number in lubrication-related service use, and multiple parts sources specifically identify it as an oil drain plug or oil pan sealing gasket rather than a large formed engine gasket.
Key Features
- Genuine Volvo Penta OEM part number 20579690.
- Listed in current sources as a gasket / sealing ring.
- Common application references identify it as an engine oil drain plug gasket / sealing ring.
- Reported dimensions from current aftermarket references include approximately M24 x 22 and, in inch-format listings, about 0.875 in ID, 1.294 in OD, 0.078 in thickness. These should be treated as reference dimensions and confirmed against the exact serial-numbered application.
- Current cross-reference listings associate this number with replacement references such as Elring 729.590, DT 2.11432, Febi 103152, and Ajusa 20005600.
Engine Compatibility
Current source coverage points to lubrication-system service use rather than a single clearly defined marine engine family in the public Volvo Penta catalog snippet available here. Seller and cross-reference sources connect 20579690 broadly to Volvo/Volvo Penta engine applications and oil-service sealing use, so fitment should be treated as engine- and assembly-specific and confirmed to the exact serial-numbered engine or parts diagram before ordering.
Serial Number Fitment Notice
Always confirm 20579690 against the exact engine serial number and the correct Volvo Penta parts diagram before ordering. Volvo Penta directs owners and technicians to identify the exact engine, shield, or drive when locating the correct spare parts and service information.
When This Part Needs Replacement
Replace this gasket when the original sealing ring is flattened, hardened, cracked, leaking, deformed, or removed during service and no longer able to provide a reliable seal. On drain-plug and similar lubrication-system service points, renewing the gasket during reassembly helps reduce nuisance seepage and repeat service. The leak-prevention role is consistent across current application references for this part number.
Installation Notes
Install only in the correct matched Volvo Penta application. Clean the mating surfaces, inspect the drain plug or related sealing face for damage, and replace the gasket whenever wear or compression set is visible. Follow the correct Volvo Penta service information for the exact serial-numbered engine when tightening and reassembling the related component.
Alternate/Superseded Part Numbers
Current references reviewed continue to list this part under active Volvo Penta number 20579690. Some sources also associate it with earlier or cross-reference numbers including 20553989 and several aftermarket equivalents such as 729.590. Cross references should always be confirmed against the exact application before use.
Parts Desk Insight
Small sealing rings like 20579690 are easy to overlook, but they can make the difference between a clean service job and a persistent oil seep. Replacing the gasket whenever the plug or related fitting is removed is usually inexpensive insurance against repeat cleanup and lost time after service.
