Wrap the tape in the same direction of the threads.
•
Keep tension on the tape and wrap it several times working away from the
end of the NPT pipe.
•
When you have finished wrapping the Teflon smooth the loose end down
into the threads.
•
Screw the NPT-to-metric adapter on the cable entry using the proper
tightening torque. See Table 17 for more details.
