🔌 Function

Seals a fluid or pressure joint by being squeezed into its groove, so the circuit holds pressure and stays free of contamination.

⚠️ Common Signs of Failure

• Fluid, air or pressure leakage develops at the joint
• The O-ring is flattened, cut, brittle, swollen or heat-damaged
• The seal extrudes from its groove or twists during assembly
• Contamination enters the sealed circuit
• Replacement is required whenever the joint is dismantled and the seal cannot be reused

🛠️ Service Notes

• Check the groove for scoring and the ring for flats before reassembly - an O-ring that has taken a set will not reseal

📦 Condition

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