However, it is difficult to maintain airtightness, There is a disadvantage that the long pipe must be rotated to join the pipe.

In recent years, as shown in Fig. 4, tightening threads are formed on the outer circumferences on both sides of the joint pipe, and a locking protrusion is formed on the inner side of the joint pipe to insert the annular packing, the tightening cap is inserted into both ends of the joint pipe, So that the pipe is fastened to both ends of the joint pipe.

However, this structure has a problem in that the structure of the periphery of the joint pipe for pressing the inner packing to adhere to the pipe is complicated, and airtightness due to the packing is often not maintained.

In addition, when using such a conventional pipe fitting, it is impossible to confirm to which portion of the pipe the inserted pipe has been inserted and whether the pipe has been securely fastened. Thus, the annular packing portion provided inside does not come in close contact with the pipe, There was a problem that it was more difficult.

In addition, when the pipe fails to securely connect to the joint pipe, there is a problem that leakage occurs to the outside and foreign substances are injected into the pipe.

In addition, since it is not possible to directly check the diameter of the pipe to be used at the opposite ends of the pipe, it is necessary for the operator or the user to insert the pipe into the pipe There has been a problem that it is necessary to check and confirm the information written on the outer shape or the pipe or the connecting pipe in a narrow space when replacing and repairing pipes and fittings.
