nut of the male connector to firmly secure the sensor
in place. When the hex nut is tightened, the Teflon
ferrule inside the compression fitting clamps the sen-
sor tube.
NOTE
A stainless steel ferrule is available if the
Teflon ferrule does not inadequately grip.
When using the metallic ferrule, care must be
taken to avoid over tightening and damaging
the sensor tube. If the male connector leaks
during insertion or retraction, replace the O-
ring in the male connector.
