954322 Fitting Nut | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta 5/16 inch union nut, weighing 0.018 kg and covering 289 applications across the D, MD, TMD, MB, AQ and AD series. It consolidates 180173, 807060 and 809992, one of which was catalogued earlier under oil pipe. The fuel line fittings group exists because Volvo Penta supplies its fuel filters and water separators without connectors or union nuts, so the fittings for the pipe size in use have to be ordered alongside the filter. Size is the ordering detail here: 954323 is the same union nut in 3/8 inch.

🚤 Compatibility

• Engine Family: D, MD, TMD, MB, AQ, AD, AQAD, BB, TAMD, MS, B, DP, SP, HS, AQD, KAD, KAMD
• HP Range: 13-190 HP

🔌 Function

Clamps the pipe end into the fitting body, compressing the ferrule to make a fuel-tight seal.

⚠️ Common Signs of Failure

• Persistent seep at the union that will not tighten out
• Thread damaged, crossed or stripped
• Flats rounded from being gripped with the wrong spanner
• Internal seat bruised or scored
• Corrosion seizing the nut to the fitting

🛠️ Service Notes

• Order by pipe size, not by appearance - 954323 is the 3/8 inch nut and looks very similar
• Fit a new ferrule at the same time and pull the joint up square
• Check for fuel leaks with the engine running and again once warm before closing up the engine space
• Part of the Volvo Penta fuel line fittings group. Volvo Penta supplies its fuel filters and water separators without connectors or union nuts, so the fittings for the pipe size in use are ordered alongside the filter.
