PIPE JOINT |
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. |
