  • ※3 Fire and Equipment Safety Center
    of Japan type rated product (size 20)
  • ※4Fire and Equipment Safety Center
    of Japan type rated product
    (pressurized water feed 20K)

Features

 

  • ①Tube
    We use SUS
  • ②Flange（JIS10K）
    Flanges can be changed to 20K etc. specification models.
    Standard flange materials are SS400, and can be changed to SUS304, 316 etc.
  • ③Braiding
    Maintains pressure resistance without losing flexibility.

●Please contact us regarding refrigerant applications
