This banjo bolt for oil line use fits lubrication systems of older vehicles with engine layouts comparable to the Citroën 2CV. The bolt provides a secure, leak resistant connection between oil line and housing, using a central passage and cross hole for oil flow. The dimensions match an M7 thread and a small orifice in the head. The bolt is suitable for metal line systems with limited space around the mounting point. The design supports controlled oil circulation between engine parts and limits pressure loss inside the line. It works with standard sealing rings for banjo style hydraulic connections.
