1. 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. Please do not use plastic fittings.
  2. When you use our products, please refer to "Precautions for Use." ("The Precautions for Use" is also available at the product specifications of E-SJSD, which can be downloadable from here.)
  3. In terms of chemical resistance, please refer to "Chemical Resistance Data."
  4. The outer layer of E-SJSD is made of polyurethane. Please keep in mind that the outer layer of E-SJSD does not have any resistance against chemicals and solvents.
  5. Although the inner layer is made of ETFE fluorine, please make sure whether or not E-SJSD is usable for high purity fluids before you use.
  6. Although the inner layer is resistant to fluids, depending on working environments, the fluids would be permeated through the inner layer, resulting in the danger of swelling and degradation of the middle or outer layer.
  7. Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose (Dissipative Type) does not have the function of getting rid of already charged fluids. Please take another approach to deal with.

Case Study

Problem: Inadequate Measures against Static Electricity: A Story from Regular Audit

Company A has been using a Teflon hose. However, the recent audit pointed out that the Teflon hose does not have any measurements against the static electricity. Thus, Company A now has to look for an alternative hose that can stand against solvents.

HAKKO Solution:

HAKKO proposed E-SJSD: Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose (Dissipative Type) and provided a sample. An inner layer of E-SJSD is made of conductive ETFE fluorine. A middle layer is made of conductive polyurethane with stainless steel wire. The inner layer shows higher levels of solvent resistance. Also, E-SJSD is a perfect hose composition to deal with the static electricity. As a result, after Company A evaluates E-SJSD, Company A is satisfied with the solvent resistance and anti-static levels of E-SJSD.

Frequently Asked Question

Question: What is the characteristic of E-SJSD?
Answer: E-SJSD meets the international guideline on static electricity. With special structures of the hose, E-SJSD prevents the generation of static electricity, resulting in the creation of safe work environment. If you transport a high flammable fluid, we strongly recommend you to consider E-SJSD.

Question: What does "Dissipative" mean?
Answer: "Dissipative" is one of the classifications of surface resistivity. In terms of electrical resistivity, "Conductive" is defined as 10³~10⁵Ω-m, "Dissipative" is defined as 10⁶~10⁸Ω-m and "Anti-Static" is defined as 10⁹~10¹³Ω-m. For the purpose of suppressing the levels of static electricity, it is said that "Conductive" comes first, "Dissipative" comes next, and "Anti-Static" comes last.
