cone to help prevent galling and facilitate sealing. Insert the tubing into the

4. Tighten the gland nut to a torque of 25 ft-lb.
Note
A weep hole has been designed into the transmitter for safety and leak detection. If fluid
begins to leak from the weep hole, isolate the process pressure, disconnect the
transmitter, and reseal until the leak is resolved.
