🔌 Function

A banjo nipple forms the through-flow union between a fluid line and a component port, letting fuel, oil or coolant pass while the joint is clamped and sealed. It provides a compact right-angle or in-line take-off where a straight threaded fitting cannot be used.

⚠️ Common Signs of Failure

• Weeping or dripping fuel or oil at the union joint
• Loss of line pressure or air being drawn into the fuel system
• Damaged, rounded or stripped threads preventing correct torque
• Corrosion, pitting or scoring on the sealing faces
• Blocked or restricted internal passage causing poor delivery to the component

🛠️ Service Notes

• Fit new sealing washers on both sides of the union every time it is disturbed; used washers have already crushed and work-hardened and will not seal again reliably
• Check the drilling through the nipple is clear before fitting, and that the mating faces on the union and the component are clean, smooth and undamaged
• Support the pipe or hose so it is not twisted or pulled as the nipple is tightened, and let the union find its own natural angle before final tightening
• Tighten only to the figure given in the workshop manual for your engine — overtightening crushes the washers out, distorts the union and stretches the threads, and the joint then leaks whatever you fit
• Run the system up to working pressure and check the joint for weeping, then check it again after the first period of running
