COPPER PIPE FOR CONNECTING COMBINATION FAUCET
To provide a high-strength copper pipe for connecting a combination faucet, that does not require an O-ring backup ring, has a small number of parts, can reduce mounting man-hours, and has no reduction in wall thickness or swelling of an inner peripheral surface.SOLUTION: The copper pipe 1 for connecting the combination faucet, that connects a combination faucet body and a main cock comprises: an annular flange part 7 having a thick part 2 protruding radially outward at a tip part inserted into a connection hole of the combination faucet body; and a plurality of annular bead parts 8 in which the thick part 2 on a tip side of the flange part 7 projects radially outward. The plurality of bead parts 8 have a smaller diameter than the flange part 7. Of the plurality of bead parts 8, a bead part 81 on the flange part 7 side is adjacent to the flange part 7.SELECTED DRAWING: Figure 2
【課題】Оリングのバックアップリングが不要で、部品点数が少なく、取付工数を削減することができるとともに、肉厚の減少や内周面の膨らみがなく、強度の高い混合栓接続用銅管を提供する。【解決手段】混合栓本体と元栓とを連結する混合栓接続用銅管１において、混合栓本体の接続孔に挿入される先端部に、肉厚部２が径方向外側に張り出した環状のフランジ部７と、フランジ部７より先端側の肉厚部２が径方向外側に張り出した環状の複数のビード部８とを備える。複数のビード部８は、フランジ部７より小径である。複数のビード部８のうち、フランジ部７側のビード部８１は、フランジ部７と隣接している。【選択図】図２
