Notice before using hoses and tubes

1. The performance and durability of hoses and tubes are largely influenced by the ambient temperature, fluid temperature, and fluid type. Choose a hose or a tube corresponding to the temperature and the fluid.
2. Use the hose or tube within the working temperature limit and below the maximum working pressure.
3. For the hose and tube that anticipate a hardening or sudden expansion by the fluid used (chemical, agent, acid, alkali, oil, paint etc.), do not use the hose or tube in the maximum upper limit (refer to the article for the chemical resistance in the catalog). Especially, when using a strong toxic chemical, high concentrated acid or alkali, etc., please consult us in advance.
4. For painting, use the Sun Paint Hose (PB-with a ground wire), Sun Paint Hose (PB-easy?FUB-easy) or Conductive Air Hose, UB-easy Air Hose as there are possibility of fire etc., by the electrostatic charge.
5. For foods, use a food hose. Even if the hoses or tubes are conforming to the guidelines, ordinances etc. of the Ministry of Health, Labour and Welfare, check them carefully before use as the odors or tastes may be sensed differently from person to person. For fatty foods, please feel free to contact our sales staff.
6. For special purposes other than above, please feel free to contact our sales staff.

Notice for using hoses and tubes

1. Do not use the hoses or tubes in less than minimum bending radius as it may deteriorate the performance and shorten the life time. If the minimum bending radius is not indicated in the catalog, homepage, or instruction manual, please contact us.
2. For attaching a hose or tube, do not bend too much around the area close to the brackets. It may cause damages in an early stage.
3. Give some allowance in piping as the length of hoses and tubes may be elastic by the inner pressure.
4. Do not give impact on or drag the hoses or tubes, and do not place the hoses or tubes under a vehicle or a heavy object. For the parts which may be bumped into by hard objects such as metals or concrete or the parts which may be contacted by other objects because of vibration or bending,protect these parts with cushioning materials, protective equipment, or springs before use.
5. Do not use hoses or tubes at the maximum working pressure for using with equipment that cause a vibration or an impact.
6. Before using hoses or tubes, never forget to check whether there are no kinks or twists.
7. Do not damage the hoses or tubes with a sharp object (including the package opening). It may cause a burst.
8. Use the main cock to stop the water flow. Open or close the valve slowly for adjusting pressure.
9. The tube without reinforcement material cannot be used for pressurized applications. However, FA Tube, Sun Tech Coil, and Connect Coil are exculuded.
10. Please take care so that you won’t get hurt from the edge of reinforcement material when cutting the Super Sun Spring Hose.

Notice for using bracket assemblies

1. When inserting a telescopic part of a nipple, do not dip oils or give fire to the hose, tube, or the telescopic part of the nipple. If it is difficult to insert, warm the hose or the tube with lukewarm water.
2. Choose a nipple which is appropriate for the hose or tube size, use the nipple in which telescopic part is bigger than the inner diameter of the hose or tube, and insert the nipple into the hose or tube completely. Use a nipple which has no burr or edge. An edge or burr may cause a burst or disconnection of the nipple.
3. Fasten the band on the center of telescopic part by using specified tightening torgue. When the temperature is high, the hose and tube may become softened. Please refasten the band from time to time.
4. Do not use metal wires etc. in place of hose bands and fasten excessively, do not give impacts on the hose or tube with a tool such as a hammer.
5. Please consult us about the bracket type and the materials/characteristics of the hose and tube, because there are possibility of fluid leakage,bracket disconnection, and a burst by the permanent deformation of the resin after the bracket assembling.
6. For the hoses, never use the outer surface seal one-touch bracket for tubes.

Inspections

1. Never fail to conduct a visual inspection (flaws, hardening, softening, color changes, etc.) of hoses and tubes for daily use.
2. Never fail to conduct a regular inspection once a month during use of a hose or tube.
3. If following abnormalities are found in the daily or regular inspections, discontinue to use the hose or tube immediately and replace it with a new one.
• ①Abnormalities around metal parts ... Local expansion, swelling, curving and leakage
• ②External flaws ... Outer surface flaws, cracks and water immersion into the reinforcement layer
• ③Peeling off of the inner and outer layers
• ④Other remarkable deterioration (hardening, oil expansion, cracks, swelling, adhesiveness, deformation, twist, etc.)

For storage

• After the use, wash and remove the residue on the hose or tube, and keep it in an airy place without direct sunlight.
  For the storage of the hose or tube, do not bend or pile up too much, or do not put anything on the hose or tube.

For disposal

1. Dispose the tube or hose after use according to the disposal method provided by the local government.
2. The product containing PVC may generate dioxin if incinerated in less the 800 ℃ .
