Product Summary

• Material standard

  Uses the same material as SUS304 pipe stainless steel pipe (JIS G3459) or a standard material equivalent to or higher than that, and has excellent corrosion resistance and resistance to rust. (Component content: 18Cr-8Ni)

• Screw standard

  Parallel thread for taper male thread [Symbol: PS (Rp)] or internal thread type pipe fitting that requires taper female thread [symbol: PT (Rc)] (conforms to JIS B0203). Suitable for joining pipe nipples, other pipe material parts, fluid equipment, etc. with pipe male thread (PT) for pipes whose main purpose is tightness.

• 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 seal 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 male screw. Apply sealant from the top and apply sealant to the female thread side to secure tightness.

• Inspection pressure

  Leakage(pneumatic)	0.5Mpa(5.1kgf/cm2)
  Pressure resistance(water pressure)	2.5Mpa(25.5kgf/cm2)
