The invention provides a novel two-ferrule tube fitting which is formed by a fitting body, nuts, front ferrules and rear ferrules. The novel two-ferrule tube fitting is characterized in that the front ends of the front ferrules are matched with horn mouths of the fitting body, and the front ends of the rear ferrules make contact with the inner arc surfaces of the rear ends of the front ferrules. The nuts are screwed onto the fitting body, so that included angles are formed between the oblique planes at the bottommost portions of the nuts and the perpendicular surfaces of the rear ends of the rear ferrules. Tubes are inserted in from the tails of the nuts and abut against inner steps of the fitting body. When the nuts are screwed tightly, the nuts propel the front ferrules, enable the front ends of the front ferrules to shrink under the action of the horn mouths of the fitting body and enable the tubes to be pressed in, and then the first seal and the first tightening function are achieved. When the nuts are continuously fastened, the force exerted on the rear ferrules is increased, the arc surfaces of the front ends of the nuts and the inner arc surfaces of the rear ends of the rear ferrules are extruded to shrink, the included angles between the oblique planes at the bottommost portions of the nuts and the perpendicular surfaces of the rear ends of the rear ferrules are gradually eliminated to produce lever acting force and enable the front ends of the rear ferrules to be clamped into the tube better, and then the second seal and the second tightening function are achieved. Connecting strength and sealing performance are more reliable.
