Beschreibung
Zusammenfassung:	A screw coupling joint having a sealing portion between an outer circumference formed in convex in an axial direction of the coupling joint at the end of the male screw portion and an inner circumference formed in taper at an inner part of the female screw portion. The female screw portion has a stopper end positioned to be contacted, when the coupling joint is assembled, by the inner end of the male screw portion. The taper is between 1 DEG and 3 DEG and the inner diameter D1 of the female screw and the outer diameter D2 of the male screw have the relationship D2>D1 at a tangent point therebetween. The end of the male screw portion and the end of the stopper are vertical or perpendicular to the axis of the coupling joint.
