Metric Thread NPT Thread
World-wide most commonly used type thread
Characterized by its major diameter and its pitch
Designated by the letter M followed by the value of the nominal diameter and the pitch, both expressed in millimetres and separated by the multiplication sign '' (i.e. M12 x 1.5)
NPT Thread = National Pipe Thread
Taper rate for all NPT threads is 1/16
The taper on NPT threads allows them to form a seal when torqued as the flanks of the threads compress against each other, as opposed to straight thread fittings
PG Thread PG Thread
PG Thread = Panzer-Gewinde
  (also Panzer-Rohr-Gewinde)
German thread type
Depth of thread smaller than NPT or Metric, but   larger flank angle
BSPP Thread = British Standard Pipe Parallel   Thread
Parallel (straight) thread with a constant   diameter, denoted by the letter G
Symmetrical V-thread in which the angle between   the flanks is 55 (measured in an axial plane)
One-sixth of this sharp V is truncated at the top   and the bottom
Threads are rounded equally at crests and roots   by circular arcs ending tangentially with the   flanks
The theoretical depth of the thread is therefore   0.64 times the nominal pitch

Note: Torque for dome nuts was determined using a metal rod. It may vary for cable, depending on the crush resistance of the cable. We recommend to determine the actual torque empirically, testing the actual cable used. The values shown above are for reference only. 
Note: Nylon strain relief fittings installed in a threaded connection and exposed to elevated temperature should be retained with a sealant such as Locktite to avoid a loose connection when temperature fluctuates.
