Updated: 4/28/2022

* 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 '×' * 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 = Panzer-Gewinde (also Panzer-Rohr-Gewinde) * German thread type * Depth of thread smaller than NPT or Metric, but larger flank angle Part Number Index sorted By Thread Types & Sizes: Metric Threads NPT Threads PG Threads ---- TORQUE RECOMMENDATIONS FOR STRAIN RELIEF FITTINGS

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. ---- Nema RatingsIP Ratings ---- provides cable products at competitive prices with exemplary customer service.
