⚙️ Key Features

• Consolidates 10886, 803687 and 804498
• 116 applications across six engine and drive series
• One of four fitting nuts listed in this group

🔌 Function

Draws the pipe end and its ferrule into the fitting body, making the seal at the joint as it is tightened.

⚠️ Common Signs of Failure

• Weeping at the union however tight it is pulled up
• Thread stripped, crossed or picked up
• Nut rounded off at the flats from repeated tightening
• Seat inside the nut scored or bruised
• Corrosion locking the nut onto the fitting body

🛠️ Service Notes

• Renew the ferrule with the nut — a used ferrule will not re-seal reliably on a fresh face
• Tighten to feel, not to force: on a fitting this small the thread strips long before the joint stops leaking
