Parts Desk Insights

Best use case: Choose 18665 when the Volvo Penta turbo connector or turbocharger diagram for the engine calls for this gasket.

Common mistake: Treating a similar-looking gasket as interchangeable. The same turbo connector assembly can include several gaskets, a sealing ring, and a clamp.

Sizing and fitment guidance: Match the engine model, serial number, diagram position, and current or earlier part reference. If you are servicing a D41, AD41, or TAMD41-family engine, verify the turbo connector diagram before ordering.
