挟む必要があった。2. Description of the Related Art Flexible pipes with small cap nuts (small diameter side piping materials) are used as piping materials with different diameters (large diameter side piping materials).
Conventionally, as shown in FIG. 3, when connecting in a sealed state with an outer screw that is screwed into one of the small diameter side cap nuts 101, as shown in FIG.
On the other hand, an adapter 110 having a cap nut 104 that is screwed to the large diameter outer screw 103 is used on the other side.
A small-diameter packing 106 is sandwiched between the adapter 110 and the small-diameter side piping material 105, and the adapter 110
It was necessary to sandwich the large-diameter packing 108 between the large-diameter side pipe material 107 and the large-diameter side pipe material 107.
