Volvo Penta 18818 – Gasket (Drain Plug Crush Washer)
Part Number: 18818 | Brand: Volvo Penta | Type: OEM Gasket / Drain Plug Sealing Washer | Sold: Individually
This is the genuine OEM drain plug sealing gasket for selected Volvo Penta diesel applications. It is a crush-style sealing washer — designed to compress and form a leak-free seal at the drain plug seating surface. Reusing a previously compressed gasket is a common cause of post-service seepage; replacing it with a fresh OEM washer at every service is the correct practice.
Specifications
- OEM Part Number: 18818
- Type: Gasket / crush-style drain plug sealing washer
- System: Engine oil or fluid drain point
- Approximate Weight: 0.004 kg
- Sold: Individually
Compatible Applications
- Volvo Penta D70B – drain plug sealing application
- Selected older Volvo Penta diesel engine applications – confirm by engine serial number
Public compatibility references for this gasket are limited. Always confirm part number 18818 against your exact engine serial number and the applicable Volvo Penta parts diagram before ordering.
When to Replace
Replace this gasket whenever the drain plug is removed for service. A crush-style washer is designed for single use — once compressed, it will not re-seal reliably. Also replace if oil seepage or weeping is present at the drain plug seating surface.
Installation Notes
- Confirm the correct part number against your engine serial number before installation.
- Clean the drain plug and seating surface before fitting the new gasket.
- Do not reuse the old compressed washer.
- Torque the drain plug to the specification in the applicable Volvo Penta service manual.

Parts Desk Insights
Best use case: This is the correct service part for any routine oil or fluid drain service on applicable Volvo Penta diesel engines. At under $5, it is one of the lowest-cost items in a service kit — and one of the most overlooked. Replacing it every time the drain plug comes out is the simplest way to avoid a slow seep after an otherwise clean service.
Common questions: The most frequent issue is customers trying to reuse the old gasket or substituting a generic hardware-store washer. Crush-style sealing washers are sized and material-matched to the seating surface — a generic substitute may not compress correctly or may not seal at the same torque spec. When in doubt, use the OEM part and replace it fresh every service.
