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 pipe joint suitable for use particularly in refrigerant piping, the pipe joint not causing corrosion due to contact between different kinds of metals even if a pipe consisting of aluminium or other metal is used, improving the efficiency of pipe connection work and the quality of the connection by eliminating the need of forming a flare on the pipe, and not likely to become loose. A pipe joint comprising a flare joint body (1), a cap nut (2), and a stop ring (3). The rounded pressure-contact sloped surface (32) of the stop ring (3) makes contact under pressure with a diameter reducing tapered section (5) at the tip of the flare joint body (1) to form a seal by mutual contact between the metal surfaces. The stop ring (3) is provided integrally with a claw section (36) which bites into the outer peripheral surface (10A) of the straight tip (10) of the pipe.
