⚙️ Key Features

• 309 applications across six engine series
• A common small sealing ring rather than a model-specific one
• Quantity varies by assembly, most commonly one

🔌 Function

Seals a threaded or spigoted joint by deforming between the two faces as they are tightened.

⚠️ Common Signs of Failure

• Slow weep or damp film at the joint after running
• Ring flattened, hardened or split on removal
• Ring stuck to one face and torn when the joint was opened
• Drip that returns soon after the joint is simply retightened

🛠️ Service Notes

• The published weight is too low to identify the part by, so order strictly by part number
• Renew rather than reuse — retightening a flattened ring is what usually turns a weep into a drip
