Banjo bolts are hollow bolts used with fluid systems to control the flow through fluid delivery lines and other components. The hollow interior of the banjo bolt allows fluid to flow inside and exit through a small hole at the side. The bolt can lock into a system to control fluid performance and pressure. Banjo bolt fittings are used where the fluid in the fluid lines is under pressure.
