⚙️ Key Features

• 0.016 kg
• Supersedes 941818

🔌 Function

Seals the face of a threaded joint or plug, crushing slightly to fill the surface.

⚠️ Common Signs of Failure

• Seeping or a wet film around the joint after running
• Ring flattened, split or bedded hard into the face
• Sealing faces scored or picked up
• Joint needing repeated re-tightening to stay dry

🛠️ Service Notes

• Sealing rings are single use — fit a new one whenever the joint is disturbed
• Check both sealing faces are flat and clean; a scored face will defeat a new ring
