Flexible Fluorine (ETFE) Resin Tubing (Dissipative Type) [Model Number: E-SJD]

Cautions:

Due to the laminated structure tubing, please use the joints to seal an inner surface of the hose.
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.
When you use our products, please refer to "Precautions for Use." ("The Precautions for Use" is also available at the product specifications of E-SJD, which can be downloadable from here.)
In terms of chemical resistance, please refer to "Chemical Resistance Data."
Although the inner layer is made of ETFE fluorine, please make sure whether or not E-SJD is usable for high purity fluids before you use.
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.
Flexible Fluorine (ETFE) Resin Tubing (Dissipative Type) do not have the function of getting rid of already charged fluids. Please take another approach to deal with.

Case Study

Problem: Conductive rubber hose is not sufficient in terms of chemical resistance.

Company A has been using conductive rubber hose, but due to its low chemical resistance, Company A has to replace the hose frequently, leading to lower production and increase of the maintenance costs.

HAKKO Solution:

HAKKO proposed E-SJD: Flexible Fluorine (ETFE) Resin Tubing (Dissipative Type) and provided a sample. An inner layer of E-SJD is made of conductive ETFE fluorine. A middle layer is made of conductive polyurethane with stainless steel fiber. The inner layer shows higher levels of chemical resistance. Also, E-SJD is a perfect tubing composition to deal with the generation of the static electricity. As a result, after Company A evaluates our E-SJD, Company A is satisfied with the chemical resistance and anti-static levels of E-SJD.

Frequently Asked Questions

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

Question: We would like to use E-SJD-6x9 and E-FTS-6×9-R1/4. If the seal tape is attached around the screw part to prevent the leakage, the resistance value will go up. Do you have any solutions on this?
Answer: There are three possible solutions. 1: Insert the ground wire between the HEX part and the nut of E-FTS and tighten the nut. (However, please note that grounding is possible, but the nut is not tightened to the end part. Thus, the tightness and pressure resistance may be lowered. 2: Wrap the ground wire around the R-threaded portion of E-FTS. (Wrap the ground wire between the HEX part of E-FTS and the equipment where R screw is installed.) 3: Wrap the ground wire around E-FTS main body of HEX Part.

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.

Test Sample and Length	Resistance Value
E-SJD-6$\times$9 1m	84K$\Omega$
E-SJD-6$\times$9 5m	103K$\Omega$
E-SJD-6$\times$9 10m	115K$\Omega$

E-SJD-8$\times$12 5m	137K$\Omega$
E-SJD-8$\times$12 10m	170K$\Omega$

Measurement method: HAKKO original fittings are attached to both ends, and the resistance value between the fittings is measured by an insulation resistance meter. (However, in order to accurately measure the resistance value for a product with conductive line layers, please do not attach the lead rods on the line layer.)
