Volvo Penta 21450768 is a genuine OEM connector used in the inlet and exhaust system on selected Volvo Penta marine diesel applications. Volvo Penta's official parts shop identifies part number 21450768 as Connector, and current dealer listings consistently place it in D4/D6 exhaust-system use.
Based on current market and dealer references, this part is commonly described as an exhaust elbow water connector / exhaust-system connector for selected D4 and D6 engines. Multiple current listings associate it with the elbow connection in the exhaust-cooling side of the system, and one dealer notes that two are normally used when replacing the exhaust elbow, while some shaft-drive installations may use one.

Serial Number Fitment Notice
Fitment should always be confirmed by engine serial number before ordering. Volvo Penta's official shop specifically advises identifying the exact engine, shield, or drive when locating the correct replacement part, because the same part family can be used across multiple installations and configurations.
When This Part Needs Replacement
Replace this connector when the original shows cracking, hardening, distortion, sealing damage, corrosion at the connection points, or leakage around the exhaust elbow / water passage area. It is also a smart replacement item when servicing the related exhaust elbow assembly, especially on engines where the connector is already being disturbed during disassembly. That matches the way current dealers market this part alongside elbow service.
Installation Notes
- Confirm fitment by serial number first.
- Inspect the connector along with the exhaust elbow, related sealing surfaces, and the required O-ring where applicable. One current listing specifically notes O-ring 969415 for sealing this connector.
- Check whether the installation uses one or two connectors before ordering.
- Follow Volvo Penta service procedures for the exact engine package and exhaust arrangement.
Alternate/Superseded Part Numbers
Current dealer references show 3819016 as an earlier superseded number for Volvo Penta 21450768. Current official Volvo Penta listings present 21450768 as the active part number.
Parts Desk Insight
This is the kind of part that is easy to overlook during exhaust work, but it can make the difference between a clean repair and a comeback leak. When a D4 or D6 elbow is already apart, checking the connector, O-ring, and surrounding sealing surfaces together is usually the smarter move than reusing tired connection pieces in a hot, wet exhaust environment.
