5.4 Pressure connection via the G ¼ female thread (Figure 11)
Be sure to use a suitable seal. Do not install the seal using tools or pointed/sharp objects. Ensure that the
sealing surfaces on the device and the measuring point are clean and intact. Only use straight (not tapered)
G ¼ male threads with the PAC50. Only use screw connections that seal the external flange axially and that
have a maximum screw-in depth of 9 mm. Using incorrect connection threads may damage the device. Avoid
tilting the thread during insertion. You should maintain a tightening torque of 1.5 Nm ± 0.5 Nm. This value
must not be exceeded. The unused G ¼ female thread must be sealed using the supplied dummy plug. Insert
the seal for the dummy plug and tighten to 1 Nm ± 0.3 Nm.
