Banjo Bolt Fittings



The banjo bolt fitting has a hollow bolt that is installed through a round hollowed out chamber with a hose fitting incorporated onto the chamber. The hollowed out chamber and hose fitting resemble the shape of a banjo, hence the name banjo bolt. The banjo bolt uses a sealing washer on each side of the hollowed chamber that should be replaced during reassembly.

Banjo bolt fittings are used where the fluid in the fluid lines is under pressure.

To install:

  1. Using new sealing washer on either side of the banjo fitting, install the banjo bolt and carefully tighten to specification. The sealing washers should be slightly "crushed" between the banjo bolt the banjo fitting and the component.
