To facilitate a good connection please ensure any surface contamination or oxidation is removed from the mounting pipe prior to installation (this is easily achieved using Scotch Brite pads).

The FT035 is typically fitted at the factory when ordered by customers, but can be carefully removed or added using non-marring tweezers by customers wishing to modify the grounding scheme of the sensor.
