What is a Banjo Bolt? What is a Banjo Fitting?
Banjo fittings are frequently used to pass pressurized fluid. They are most often seen in brake systems, but there are lots of other applications for Banjo fittings. The banjo fitting is the banjo shaped fitting while the banjo bolts are hollow bolts with a hole on the side. This hole allows fluid transfer into the other part of the fitting, which is also hollow. You will need both a banjo bolt and banjo fitting to create a system. The banjo bolt passes through the center of the fitting, which also has a hole in it. The banjo fitting has flat surfaces which are normally sealed with a copper banjo bolt washer. Those seals allow fluid to pass around the bolt, which means the holes do not need to line up unlike a standard threaded fitting, making installation of lines easy.
