⚙️ Key Features

• OEM Volvo Penta part number 11423710
• System group: Lubricating and Oil System
• Net weight approximately 0.41 kg (0.408 kg)
• Fits D13 and D16 marine engines plus TAD and TWD industrial and generator-set engine families

🔌 Function

The adapter forms a sealed connection point within the engine's lubricating oil circuit, joining oil lines or components with the correct port and flow path. It maintains oil pressure and directs lubricant to the intended part of the system.

⚠️ Common Signs of Failure

• Oil weeping or dripping from the adapter joint or its sealing face
• Loss of oil pressure or fluctuating pressure readings
• Damaged, corroded or cross-threaded connection preventing a proper seal
• Visible cracking or distortion of the adapter body
• Repeated seal or gasket failure at the connection point

🛠️ Service Notes

• This is an oil-circuit fitting for the D13/D16, TAD and TWD 11- to 16-litre engines — unlike several other reduction nipples of the same name that live in the fuel system, so check which circuit you're actually working on before ordering
• At 0.408 kg it is one of the heavier fittings in this family — renew the sealing washer whenever the joint is disturbed rather than reusing a compressed one
