<Remarks/Precautions>

  • If the fluid is liquid and the hose is used in overhead piping, the weight of the internal fluid may cause the hose to sag, so please use appropriate support fittings.
  • The inner surface is also uneven, and solids may accumulate, so please be careful when using a slurry fluid.
  • Due to the high flexibility of the main body, it may protrude sideways when pressurized.
  • Please contact us for non-standard specifications (diameter, length, etc.).
