Flexible Fluorine (ETFE) Resin SUS Spring Wire Hose (Dissipative Type) [Model Number: E-SJSD]

Cautions:

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.
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.)
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-SJSD 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 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.

Test Sample	Length and Resistance Value Data	Length and Resistance Value Data	Length and Resistance Value Data
	1m	5m	10m
E-SJSD-12	108K$\Omega$	155K$\Omega$	180K$\Omega$
E-SJSD-15	22K$\Omega$	39K$\Omega$	48K$\Omega$
E-SJSD-19	30K$\Omega$	45K$\Omega$	72K$\Omega$
E-SJSD-25	121K$\Omega$	145K$\Omega$	150K$\Omega$

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.)

Product Name	Materials, Characteristics
EIGHTLOCK Ferrule Fittings [Model Number: E-ELF]]	Material: Body: SCS16, Nut and Ring: SCS13 (Sleeve: POM) You can replace a hose even though the hose needs replacement, since EIGHTLOCK Ferrule Fitting is a nut ferrule fitting. You can install and detach the fitting on site. You can make use of a wide range of usages such as pipes for chemicals, food, beverage and alcohol. The nipple end is less likely to accumulate fluids, so you do not have to worry about contamination very much.

EIGHTLOCK S Fittings [Model Number: E-ELS]]	Material: SUS304 (Body, Ring, Nut), POM (Sleeve) Our Nut Type Original Made-in-Japan Fittings Since the inner layer of the fltting is flat and does not use the rubber packing, fluid accumulation is unlikely to occur. Thus, it is easy to wash out. Since you do not need hose clamp and the controlling torque value, you can standardize how to install the fitting.

EIGHTLOCK B Fittings [Model Number: E-ELB]]	Material: BSBM (Body, Ring, Nut), POM (Sleeve) Our Nut Type Original Made-in-Japan Fittings Since the inner layer of the fitting is flat and does not use the rubber packing, fluid accumulation is unlikely to occur. Thus, it is easy to wash out. Since you do not need hose clamp and the controlling torque value, you can standardize how to install the fitting.

EIGHTNIPPLE S Fittings [Model Number: E-FTS]]	Material: SUS316L SUS316L is superior in corrosion resistance, so you can transfer a wide range of fluids. Two-stage flat nipple structure which maximizes hose pressure Our Original Barb Nipple Fittings Made-in-Japan Fittings
