A pipe fitting for use with fluid-holding apparatus has a thread that matches any of several different types of pipe threads of the same diameter. Imperfect sealing is eliminated by simple means by taking adv.antage of a small chamfered area that is provided at the outer end of an in- ternally threaded bore. An external thread matching sever- al different types of internal pipe threads of the same diameter has a flared surface tapered at an angle of ap- proximately 90 degrees at its base. A sealing member 22 to seal the clearance between thP pipe fitting and the inter- nal thread ;n the fluid-holding apparatus is provided at a point corresponding to the chamfered area 24 that is posi- tioned slightly outside the periphery of the outermost root of the internal thread cut in its outer end.
