84476710 O-Ring | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta O-ring weighing 0.001 kg and listed for 17 applications across the TAD and TWD series engines. Its data is identical in every respect to O-ring 84476715 — same name, same weight and the same 17 applications — so nothing in the listing separates the two and they must be ordered by part number.

🔌 Function

Seals a static joint by being squeezed into its groove, blocking the escape of fluid or pressure past the mating faces.

⚠️ Common Signs of Failure

• Slow seep or drip at the joint the ring seals
• Ring flattened, hardened or shiny where it has taken a set
• Nicks, cuts or spiral twist marks from a previous fitting
• Ring swollen or gone soft from the wrong fluid
• Joint that reseals briefly when nipped up, then leaks again

🛠️ Service Notes

• Take the part number from the assembly you are working on rather than trying to choose by size — the listing does not separate this ring from 84476715
• Fit dry or lightly lubricated as the assembly requires, and never roll a ring over a sharp edge or thread

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
