著しく困難であることから自動化に不適切であった。However, in the former case, since the cap 1 is hemispherical and easily moves (reverses) in the flare nut 2, it is not possible to attach the cap to the sealing surface of the flare connector beforehand. Since it is possible, it has a high level of skill not to drop and invert the cap incorporated in the flare nut, and it is not suitable for automation because normal mounting and reliable sealing are extremely difficult.

することができ脱落防止が図れる。In FIGS. 3 and 4, reference numeral 7 denotes a cap 2 made of a copper material, a flare nut having a thread groove 2a formed on the inner periphery thereof,
Reference numeral 4 denotes a flare connecting tool having a thread groove 4a which forms a pair with the thread groove 2a on the outer circumference. The cap 7 has an insertion portion 11 that is coaxially inserted into the pipe line 10 of the flare connector 4, a seal flange 14 that is closely attached to both sides of the seal surface 12 of the flare nut 2 and the seal surface 13 of the flare connector 4. Blocking wall 15 for closing the tip of the conduit 10 of the flare connector 4
Is provided. The outer diameter D3 of the insertion portion 11 of the cap 7 is smaller than the inner diameter D4 of the conduit 10 of the flare connector 4, and L1 is longer than D4. As a result, the cap 7 can be inserted into the conduit 10 of the flare connector 4, and the dropout can be prevented.
