18665 Gasket | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Gasket - Part Number: 18665

This genuine Volvo Penta gasket is a precision-cut sealing component designed for the specified engine or propulsion-system joint used in the turbocharger oil-feed/return and engine fluid-line banjo joints. It is manufactured to the original Volvo Penta dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it seals a hollow-screw or banjo fluid connection so oil or fuel pressure is retained without seepage. Selection must be confirmed by OEM part number 18665, the exact engine or product model, serial number and installed configuration.
