    摘要： [Problem] To provide a pipe joint allowing reliable connection to a pipe P without flaring.
    [Means of solving problem] The pipe joint includes a flare joint body 1F, a cap nut 2, and a stop ring 3. A curved pressure-contacting slope surface 32 of the stop ring 3 contacts a slope surface 5 with reduced-diameter tip of the flare joint body 1F under pressure to establish sealing by means of mutual contact between metallic surfaces. The pipe P is grasped in a tightly pressure-contacting state using a back tooth and a front tooth formed at a tip head 37 of a substantially cylindrical thin part 35 of the stop ring 3.

    摘要： A coupling for attaching to an end of a tube, pipe, conduit or other round solid or hollow section. The coupling includes an inner body and a collar to be provided around the inner body. The inner body has an interior bore passing through at least a portion thereof to receive a tube or the like and the bore has one or more interior annular protuberances extending into the bore. When the collar is provided around the inner body it applies a circumferential compressive force to deform the inner body such that the one or more annular protuberances engage the tube or the like to seal with it.

    摘要： A tube fitting for a tube end has a female threaded member that cooperates with a male threaded member. The female member includes a tube gripping device in the form of a gripping ring or ferrule that is attached to the female member by a fungible web. Upon a partial pull-up the female engages a camming surface on the male threaded member and breaks off or separates from the female threaded member to become a separate piece so that the fitting then functions as a single ferrule tube fitting. Additional features include a steep camming angle on the camming surface to cause the ferrule to grip the tube end with a bite-type action and to form a primary seal between the camming surface and a front end of the separated ferrule. The ferrule front end, and optionally the entire female threaded member including the initial integral tube gripping device, are hardened to be at least about 3.3 times harder than the material of the tube end.

    摘要： A coupling comprises an inner body having an interior bore configured to receive a tube or the like. A collar is arranged to be axially received about the inner body. The collar being configured such that when it is forced onto the inner body, it applies a circumferential compressive force to deform the body inwardly. At least one interior annular projection defines one or more annular teeth arranged such that when a tube is received in the bore and the inner body is inwardly deformed by the collar, the one or more annular teeth engage the tube to seal with it. The inner surface of the bore comprises a plurality of circumferentially arranged projections defining a series of circumferentially spaced teeth axially spaced from the at least one annular protuberance and configured to engage the tube following compression of the inner body by the collar to prevent relative rotation between the tube and the inner body.
