The HP fuel line is sealed by the thrust ring (9).
If leakage in the area of the thrust ring (9) or the HP line (2) occurs, the emerging fuel is routed to the
leakage chamber.
The leak fuel is drained off without pressure via the leakage overflow bore (8). The leakage chamber is
sealed toward the outside by the O-rings (3).
This prevents leaking fuel from escaping.
The connection is confirmed as compliant with SOLAS by DNV and GL.
