摘要:
A ferrule type, flareless fitting is provided that includes a first fitting component (12), a second fitting component (16), a front ferrule (20), and a rear ferrule (22). The first fitting component comprises a rear ferrule recess and a front ferrule recess. The second fitting component includes a ferrule camming surface. The front ferrule is disposed between the first fitting component and the second fitting component such that a portion of the front ferrule engages the front ferrule camming surface. The front ferrule includes a flange that extends radially outward from a portion of the front ferrule that engages the front ferrule camming surface. A difference angle is defined between the front ferrule recess and an outer surface of the flange when the fitting is in a finger tight condition. The difference angle diminishes during pull up of the fitting. A rear ferrule is disposed between the front ferrule and the first fitting component such that a rear ferrule drive surface of the rear ferrule recess engages the rear ferrule when the fitting is pulled up.
