Usage of banjo fitting:
A banjo fitting has two parts, banjo bolt, and banjo, the spherical union. It is commonly used in automotive fuel/ diesel, motor oil, hydraulic systems (e.g brake) or other high pressure applications. The major advantage of banjo fitting over other pipe fitting is that, it does not need to be rotated relative to the host fitting, therefore making assembly and dis-assembly easy and quick.
How a banjo fitting works:
The banjo has a hole in it and with a washer or crush washer on the flat surface. After tightening the bolt with the banjo (metal-to-metal and elastomeric seals), the pressurized fluids can pass around the bolt and get into the bolt from the hole on the side of the bolt. So the inlet hole in the banjo does not need to align with the hole in the bolt and enhance flexibility.

Banjo fittings can be made in zinc plated steel, stainless steel, brass and other materials.
