It is manufactured to the original Volvo Penta dimensional, material and interface requirements for the documented Volvo Penta 9-litre TAD9 generator diesel application. Technical identification: Air-vent pipe in the TAD940GE fuel-system assembly; catalogue key 14. In service, it routes crankcase vapour, separated oil mist or trapped air through the specified ventilation circuit so pressure remains controlled and fluid flow is not interrupted. Selection must be confirmed by OEM part number 20553855, the exact model\/product number, serial number and installed assembly configuration.\n\u003c\/p\u003e\n\u003ch2\u003e\n 🚤 Compatibility\n\u003c\/h2\u003e\n\u003cp\u003e\n Typically suits:\n\u003c\/p\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Volvo Penta TAD943VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD952VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD951VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD950VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD940GE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD940VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD941VE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD941GE\n \u003c\/li\u003e\n \u003cli\u003e\n  Volvo Penta TAD942VE\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n \u003cli\u003e\n  \u003cstrong\u003e\n   Engine Family:\n  \u003c\/strong\u003e\n  TAD\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n ⚙️ Key Features\n\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n  Genuine Volvo Penta OEM air vent pipe\n \u003c\/li\u003e\n \u003cli\u003e\n  OEM part number 20553855\n \u003c\/li\u003e\n \u003cli\u003e\n  Technical distinction: Air-vent pipe in the TAD940GE fuel-system assembly; catalogue key 14\n \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\n 🔌 Function\n\u003c\/h2\u003e\n\u003cp\u003e\n Routes crankcase vapour, separated oil mist or trapped air through the specified ventilation circuit so pressure remains controlled and fluid flow is not interrupted.
