  1. These are fittings for piping with welding. We can machine the beveling.
  2. Above fittings for toxic gas use, approved by Japan's government, are also available.
  3. The reliability and durability under high pressure & temperature have been proven by its more than 30-year history.
  4. Since the structure is very simple, the reliability of the sealing performance is very high and these fittings are very stable against vibration or water hammer pressure.
  5. Since the seal is by direct metal contact,these fittings can be used on piping which operate under corrosive conditions, from vacuum to high pressure, from very low to high temperature.
  6. These fittings don't use any gasket so their handling is very simple and their durability is very high.
  7. Plug male threads and plug sleeves are also available.
