Cautions:

  1. Due to the yarn-reinforced hose, please use the joints to seal an inner surface of the hose.
  2. Please do not use the joints to seal an outer surface of the hose. This may result in the bursting or coming off from the hose.
  3. When you cut the spring wire, be careful not to get hurt on your hands, because the spring wire may stick out at the cross-section of the hose.
  4. When the spring wire sticks out, cut it off neatly with a nipper. For visual images of how to cut the spring hose, please click here.
  5. In case the spring wire is broken, it is impossible to restore its shape. Please replace into a new hose.
  6. E-SP does not have the features of oil-proofness. Depending on the using conditions, hose may harden if you transfer oil.
  7. When you use our products, please refer to “Precautions for Use.”
  8. In terms of chemical resistance, please refer to “Chemical Resistance Data.”

Frequently Asked Question

Question: In terms of working pressure, which is higher either E-TB or E-SP?
Answer: Some might think that in terms of working pressure, E-SP is higher, because the steel wire is included in the hose. However, the steel wire is intended for vacuum resistance. For positive working pressure, E-TB is higher than E-SP. For more information on working pressure for each size, please refer to the product pages of E-TB and E-SP.
