    Used as a joint adapter for connecting pipes and hoses. One side is provided with a pipe taper male thread (R), which is joined to a threaded joint. The other side has a bamboo shoot shape, making it difficult to pull out when inserting the hose. Final tightening with a hose band and fixing to complete the construction.
  • About inspection of screw
    All thread inspections are performed using a taper thread gauge specified in the standard number (JIS B0253) defined by the Japanese Industrial Standards (JIS standard). In addition, our inspection gauge manufacturer uses OSG (OSG).
  • Join method
    When tightening, after tightening by hand, it is necessary to tighten with torque using a tool such as a pipe wrench. However, in order to tightly bond, even if it is tightened tightly, there is a slight space between the top and bottom of the mountain in practical use, and perfect airtightness cannot be secured. Therefore, it is necessary to take measures such as wrapping seal tape (tape-like gap filling material) around the screw before assembly or applying the same liquid sealant. (It is necessary to select the type of sealing material suitable for the piping application.) Also, when assembling in a place where attention is paid to leakage, seal tape (about 2 to 3 turns) is wound around the external thread. Apply sealant from the top, and then apply sealant on the female screw side and tighten it to ensure tightness.
