How do you tighten a coupling nut?

For best results, tighten coupling nuts by angle rather than torque, whenever possible. This ensures the correct amount of preload, regardless of friction levels. Minimize twist-up by loosening the adjacent tube clamps before tightening the fluid fitting. Then, retighten the clamps after the fitting has been tightened.

What is a left hand nut?

Left hand nuts are left hand threaded. This is opposite to standard nuts which use a right hand thread. Left-hand must be installed by turning them in a counterclockwise direction to tighten. Left hand nuts are used when the screw may be subject to a counterclockwise force or torque.

Screw Handedness: Left-Hand Thread and Right-Hand Thread Screw handedness refers to the direction that a screw’s thread wraps around its shaft. Right-handed threads run clockwise, and left-handed threads run counterclockwise.

Are there left hand thread nuts?

What are coupling nuts made of?
