The adapter 1 685 720 306 / adapter 1 685 720 308
holds the pressure sensor and is screwed in between
the test pressure line/high-pressure hose and the injec-
tor (tightening torque on both ends: 25 – 30 Nm).
To permit connection to injectors with different thread
sizes at the high-pressure outlet, the adapter is pro-
vided with an adapter nut on one end which can be ex-
changed for an adapter nut with a different thread size.
Use involves removing the adapter nut at the adapter
and fitting and tightening the other adapter nut.
The scope of delivery includes two adapter nuts for the
following thread sizes:
