1556905 Sealing Ring | Genuine Volvo Penta Part

🔧 Product Description

This genuine Volvo Penta sealing ring is a formed OEM sealing component used in the engine sealing joint. It is manufactured to the original Volvo Penta dimensions and interface requirements so the mating joint retains its intended fluid, gas or contamination barrier. In service, it seals the matched engine connection against oil or coolant leakage. Fitment is controlled by the exact engine or product configuration and serialised parts list; confirm OEM number 1556905 against the installed assembly before ordering.

🚤 Compatibility

• Engine Family: D, TWD, TID, TD, TAMD, TAD

⚙️ Key Features

• Net weight approximately 0.0045 kg
• Fits D13 and D16 series engines plus TAMD162/163/165, TAD1630/1631, TWD1620/1630, TID162 and TD164 families

🔌 Function

The sealing ring seats between two mating surfaces to create a fluid-tight and pressure-tight joint. It compensates for minor surface irregularities and maintains the seal as components expand and contract with engine temperature.

⚠️ Common Signs of Failure

• Visible weeping, seepage or dripping at the sealed joint
• Hardened, brittle or cracked ring material on inspection
• Flattened or permanently deformed ring that no longer springs back
• Loss of system pressure or dropping fluid level with no other identifiable leak
• Contamination or corrosion around the joint face caused by a slow leak

🛠️ Service Notes

• Always fit a new sealing ring rather than reusing the old one — a ring that has been compressed once has taken a set and will not seal reliably a second time
• Clean the groove or seat and check it for scoring, corrosion and old sealant before fitting; a mark across the sealing face will leak however good the ring is
• Ease the ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely all the way round before closing the joint
• Do not add sealant or jointing compound unless the workshop manual for your engine calls for it, and tighten the joint or union to the figure given in that manual
• Check the joint for weeping once the engine has been run up to temperature and allowed to cool, as many sealing rings only show a leak after a heat cycle
