🔌 Function

Seals a fuel joint by deforming into its groove under compression, closing the leakage path between the parts.

⚠️ Common Signs of Failure

  • Diesel weeping at the joint or a fuel smell in the engine space
  • Air in the fuel giving rough idle and hard starting
  • Ring flattened, nicked, twisted or extruded on removal
  • Ring hardened, swollen or gone sticky
  • Score marks in the groove or on the counterface

🛠️ Service Notes

  • Renew every time the joint is opened, lubricate lightly with clean fuel, and check the groove and counterface for burrs
  • Fuel leaks are a fire risk, so pressure check the joint before the engine is run unattended
