A fluid coupling capable of indicating proper tightening includes a fitting body having a flared end with a back side. The fitting body also includes an indicator spaced a predetermined distance away from the back side. A threaded nut is positioned around the fitting body adjacent the flared end and includes a back end and a shoulder portion spaced away a predetermined distance therefrom. The shoulder portion is concentrically aligned with the back side of the flared end. The fluid fitting also includes a belleville washer(s) positioned around the fitting body adjacent the back side of the flared end, which is (are) compressed upon threading and torquing of the nut onto the threaded end of a male fitting. When a predetermined amount of torque has been applied to the nut, the indicator is visible adjacent the back end of the nut.
