Full model list at the end of this description.

⚙️ Key Features

• Closure plug for the engine-oil drain connection
• Used in the TAD11 oil-drain pump schematic
• Correct thread and sealing face
• Works with gasket 18813
• Plug only; gasket, nipple and drain hose are separate
• Engine type: Volvo Penta 10.8-litre inline six-cylinder industrial diesel

🔌 Function

Seals the oil-drain service port and prevents oil leakage or contamination entry.

⚠️ Common Signs of Failure

• Oil seepage around the plug
• Damaged or crossed threads
• Missing or hardened gasket
• Plug loosening during vibration
• Contamination entering the drain connection

🛠️ Service Notes

• Clean the threads and the seating face before fitting, and make sure the opening itself is clear of old sealant, swarf and corrosion
• Renew the sealing washer or O-ring where one is fitted rather than reusing a flattened one, and only use thread sealant where the workshop manual for your engine calls for it
• Tighten to the figure given in the workshop manual for your engine — plugs in aluminium and other soft castings strip easily, and a plug pulled up hard to cure a leak usually distorts the seat and makes it worse
• Where the plug closes an oil, fuel or coolant passage, run the engine up to temperature afterwards and check the joint under pressure before signing the job off
• Keep removed plugs paired with the holes they came out of during a strip-down — plugs of very similar appearance often differ in thread, reach or sealing type
