Banjo / Hollow Bolt

Banjo (hollow) bolts are mostly used for connection sealing in oil and water delivery pipes. They feature a dual function of fastening while still allowing for a medium flow through them. Hollow bolts are widely used in engine fuel supply systems for automobiles, ships and machinery.
