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.
