17403216 Nipple | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta nipple is a formed or machined fluid-transfer component used in the fuel-filter housing and fuel-line connection. It is manufactured to the original Volvo dimensional, material and interface requirements so the serviced assembly retains its designed alignment, sealing, load capacity and operating reliability. In service, it provides the threaded fuel-line connection at the engine fuel-filter housing while maintaining a leak-free, correctly routed fuel circuit. Selection must be confirmed by OEM part number 17403216, the exact engine/product model, serial number and installed configuration.

⚠️ Common Signs of Failure

• Fuel weeping, dripping or staining at the connection
• Air drawn into the fuel system causing hard starting or rough running
• Damaged, stripped or cross-threaded threads
• Corrosion, pitting or damage to the sealing face
• Connection loosening under vibration

🛠️ Service Notes

• Check the bore is clear before fitting — a nipple is often the feed point or restriction for a circuit, and debris left in it will starve whatever it supplies
• On tapered threads use the paste or liquid sealant specified for the fluid concerned, applied a few threads back from the open end; avoid thread tape on fuel and oil lines, where a shed shred travels downstream into filters, pumps and injectors
• Where the nipple seals on a face or against a washer rather than on its thread, fit a new sealing washer instead of curing a weep by overtightening
• Tighten to the figure in the workshop manual for your engine — these are small fittings in castings and are easily stripped, or the surrounding boss cracked
• Support the pipe or hose so it meets the nipple square and without side load, then check the joint at working pressure and temperature
