Process Connection
Use two wrenches when connecting process pipe: an 1-1/8 inch open-end wrench to hold
the hex port while connecting the process pipe; the other wrench to tighten the process
pipe or tube fitting.
When rigid process piping is used, it is important that no bending or torsional
forces be imposed on the pressure switch.
