Sae-as33514 -

Cause: Differential thermal expansion between ferrule and tube (e.g., steel ferrule on aluminum tube). Solution: Retorque to specification after system reaches equilibrium. Consider using same-material tube and ferrule.

Reduces training time. New mechanics can install AS33514 correctly on the first try, every time. It also reduces inspection time—QC can spot a loose nut from 10 feet away because the color band won't be visible. sae-as33514
