ABSTRACT OF THE DISCLOSURE: Hermetic metal pipe joint, comprising a male element with at least one external tapered thread and a female element with complementary internal threads. An end part of the male element beyond each thread has a conical seal surface and the female element has a conical seal surface with the same taper as that of the conical surface of the male element. The two conical surfaces on the male and female elements mate upon tightening of the joint. The length of the seal surface of the female element along the generatrix is greater than that of the corresponding seal surface of the male element. These two seal surfaces of the male and female elements have a taper in the range 6.25 to 9.25% relative to the axis of the conical seal surface. The length of the surface of the male element which comes into contact with the corresponding surface of the female element is between 0.5 and 2.5 mm. The end part of the male element has a nose with a conical seat surface that mates, upon tightening of the joint, with a similar conical seat surface in the inner part of the female element. These seat surfaces have the sametaper as each other, in the range 5° to 10° with respect to a plane perpendicular to the joint axes. These seat surfaces contact each other only after mating of the seal surfaces.
