Micro-Flexible Annular Hose

Micro-Flexible Annular Hose

Also known as “Micro-Flexible Tube (MF)”


With the use of SUS316 Stainless Steel, this tube:

  • Resists rusting
  • Withstands pressure, high and low temperatures

Armored stainless steel braiding used in conjunction will increase this conduit’s high-pressure capabilities.



For high-precision mechanical equipment such as:

  • Semiconductor and LCD panel manufacturing devices
  • Pharmaceutical processing equipment
  • Biological and food processing equipment where durability, pressure maintenance and safety are required
  • Optical fiber protection requiring air-tightness
  • Medical applications (ex: blood cooling in cryogenic heat exchangers)
  • Delivery pipe for oil, steam, air and other fluids in vacuum equipment
