Volvo Penta Seal 21403629

Volvo Penta 21403629 is a genuine OEM seal used in select Volvo Penta marine applications. Volvo Penta identifies this part simply as Seal, and the available fitment trail supports treating it as a serial-number-confirmed sealing part rather than a universal seal by appearance alone.

Key Features

• Genuine Volvo Penta part number 21403629
• Official Volvo Penta part name: Seal
• OEM sealing component for select Volvo Penta marine applications
• Best matched by exact part number, model, and serial number

Engine Compatibility
The strongest verified information confirms the part identity as 21403629 Seal, but the sources reviewed do not provide a clean model-by-model fitment list on the visible product pages. Because of that, this part should be sold as a serial-number-confirmed application seal.

Serial Number Fitment Notice
Please confirm fitment by engine, drive, or shield model and serial number before ordering. Volvo Pentas parts shop specifically directs users to identify the exact product when sourcing genuine parts.

When This Part Needs Replacement
Replace this seal when the original is leaking, hardened, cut, damaged, or no longer sealing correctly in the related assembly. Because the exact assembly location is not clearly stated in the sources reviewed, replacement is best tied to inspection condition and confirmed application. This replacement guidance is an inference based on the parts role as a seal.

Installation Notes
Install only on the correct Volvo Penta application and verify the removed part against the part number, model, serial number, and sealing location before ordering. Matching the original part exactly is the safest approach here.

Parts Desk Insight
The clearest verified fact is the part identity itself: 21403629 is a genuine Volvo Penta seal. Since the exact plain-language application is not clearly exposed in the sources reviewed, the safest Marisol Marine sale is against the exact serial number and removed-part match.
