PURPOSE:To provide easily a tube fitting in which a nut cannot be rotated with a bare hand, but the nut can be rotated to fasten by using a fastening tool such as a spanner, by breaking or removing a seal tape. CONSTITUTION:This tube fitting consists of a joint main body 11; a nut 12 screwed to the joint main body 11; an interpolation member such as a bite type spring 13 installed between the joint main body 11 and the nut 12; and a seal tape stuck along both outer surfaces of the joint main body 11 and the nut 12 installing the interpolation member. The nut 12 cannot be rotated by a bare hand because it is sealed by the seal tape, but the nut 12 can be rotated to fasten by using a fastening tool such as a spanner, because the seal tape is broken or removed by the fastening tool. |
