Banjo Bolts

A banjo fitting (also called an internally relieved bolt) comprises a perforated hollow bolt and spherical union for fluid transfer. They are commonly found in automotive fuel, oil and hydraulic systems (e.g.: brakes and clutch). The pipe connected may be either rigid or a flexible hose.The main advantage of the fitting is in high pressure applications (i.e. more than 50 bar). The name stems from the shape of the fitting, having a large circular section connected to a thinner pipe.
